I see lots of people against the idea of new Slayer positions (and one suggestion to remove Slayers entirely, which is making me go 'whut').
Welp, that's not stopping me continuing to try and at least drag one new Slayer type out of the flames, because honestly I like the idea of a Bone Slayer too much to just let it go without a fight.
I suppose I should touch each arguments separately.
First of all, the 'we don't need a new OPbroken Slayer type' argument. That is of course a very valid argument. However, I fail to see how that would count for a Bone Slayer. I mean, you eat bones. As a result you're probably going to be eating corpses a lot. You can't in some way twist eating bones into being able to eat other stuff as well. Hell, it's not even like there's a lot of attacks which include bones so being able to eat bones isn't going to make you immune to a lot of attacks. And bones aren't exactly something which can be used in so many ways as to make it OPbroken. Even more so, the chances of being able to eat enough bones as to achieve Slayer Force are very low, so in some ways Bone Slayer would be less OP than several existing Slayer types, since it doesn't make you virtually immune to a commonly used attack type and there aren't often enough bones around for you to eat yourself into Slayer Force mode.
Second is the argument that we don't need to make new Slayers for the sake of having new Slayers. That is also correct. However that's completely different from making a new Slayer type because that Slayer type just sounds like a good type of magic. Personally I think Bone Slayer wouldn't sound forced at all. You eat corpses, and use bones in your abilities (bone armour, bone claws). This in sharp contrast to something like Paper or Oil, which does sound forced.
Third is the argument that it isn't necessary to have new Slayer types. That is once again true. However does something have to be necessary for it to be added? What if it's just a fun/good/interesting idea? The idea that you should only ever add new ideas if said ideas are really necessary sounds a lot like restricting creativity. The magic type I created for my character sure as hell wasn't necessary. However I've heard from several people how they find it interesting, including the Mod who originally approved of it. Should that also have been rejected for being an unnecessary addition to what types of magic exist and are available, for being unnecessary no matter how interesting it may be?
Fourth is the person who has become allergic to the idea of Slayers due to it being hyped so much. While I can understand that, and have experienced something similar with other concepts in the past, I still have to say that even if lots of ideas around the concept are flawed it isn't good to just assume each and every part of the concept is flawed and should only be rejected and never considered. Not that I'm saying everybody would like the idea of a Bone Slayer even after considering it, but I believe that it should at least be considered before rejected, rather than that we destroy any chances of getting a new Slayer type, regardless how good it may be, because we've experienced too much stupidity regarding Slayers in the past.
I know it's a bit arrogant to be defending a new Slayer Type I myself suggested in the first place. However I feel like Bone Slayer would not be overly redundant, would not be forced, and would not be broken. Looking at the Fairy Tail manga Slayers are supposed to be bruisers. Several of their techniques are about enhancing melee attacks, with a couple of ranged additions. A Bone Slayer would easily fit the role of bruiser. They would cover themselves in bones as armour, and grow claws of bones to rip apart their enemies. They'd revel being in the middle of the battlefield, where they can keep eating the bodies of the fallen so they can keep fighting until the only things left are corpses and crows, with the Bone Slayer feasting as enthusiastically as the carrion eaters.
Does that kind of magic sound forced? I myself certainly don't think so. Bone God Slayers would have bones black as night, making them even more terrifying than the other two Slayer types, as is fitting for a type of magic meant to slay Gods. Bone Demon Slayers would have bones white as snow, making them look intimidating and strong, ready to bring down the Demons that plague the land. The Bone Dragon Slayer would have bones of a yellow-ish colour, giving them a fierce and primal appearance, like the Dragons from which they would have learned their magic.
A good test to see if a Slayer type would be over the top or redundant is ask the question: would somebody think of that type of magic even if the whole idea of Slayer magic was never thought of?
How likely is it that somebody would think of a magic type where your character eats paper, then uses abilities which mainly consist of paper? Shooting out lots of small papers and making them move in whirlwinds, covering their enemies in small cuts until they succumb to their wounds? There might be somebody who thinks of that, but the chances are slim. Anybody who wants that kind of fighting style would probably just use wind magic and make it slicing winds.
How likely is it that somebody would think of a magic type where your character eats oil, then uses oil to defeat their enemies? I'm having difficulties even thinking of abilities that include oil that aren't just spitting it at people and blinding them. If somebody were to think of using oil it would only be a part of somebody's magic abilities. A part focused on hindering people's sight. And I doubt they'd ever think of eating oil, at least as specific part of their magic.
How likely is it that somebody would think of a magic type where your character eats bones, then turns into a monster clad in bones to destroy and devour? A cannibal who has trouble controlling their urge to devour the bones of the fallen, who live up to the term bruiser by creating armour out of bones and creating claws out of bones, ripping enemies apart and feasting on them before launching themselves at their next prey? My imagination might be a bit darker than most, but I'm pretty sure this would have been thought of eventually even if Slayers were never heard of, because it isn't illogical. It may be dark and rather morbid, but it isn't like bone armour and bone claws and corpse eating are concepts you'd have trouble thinking of, that you'd really have to try and be outlandish to get that idea.
So, in the end, my argument is: I understand that we shouldn't add Slayers for the sake of adding Slayers, and that Slayers shouldn't be OPbroken, and all that. However I don't think Bone Slayer falls under any of those categories.
I mean, even without the Slayer position I would at some point probably have used my more morbid ideas and have created a corpse eater who uses bone armour, because ever since I saw a couple of examples in games and stories I thought the concept of bone armour was pretty cool. As I already said, I thought of Bone Slayer AFTER thinking 'We need a corpse eater. Wait, Shyvana has a Bone Dragon skin. Combining those two would be pretty cool'. I didn't start thinking of creating a corpse eating bone armour wearing monster after hearing about Slayers. I already had that idea in my mind, and when hearing about Slayers I thought that the ideas were similar enough that it would make more sense to just incorporate my idea into the Slayer system than to make it entirely separate magic regardless of the glaring similarities.
Also, another question: say this whole idea was rejected, and I would at some point come with an alt whose magic is actually eating corpses and growing bone armour and bone claws to become a bruiser monster. Would anybody think that I would only ever think of that idea because of Slayers? Would that idea be rejected not for being a bad idea, but because it is too similar to being a Slayer?
In fact, would anybody here reject the idea of the corpse eater, the Monster Clad In Bones, not as a Slayer type, but as a type of magic entirely?
Because if people don't think the idea itself is bad, I don't see why it should do any worse if you do the sensible thing and just make it a Slayer type. The only difference would be an official acknowledgement of its existence and some increased regulation.
EDIT: As for the idea of removing Slayers entirely...I think that's too fundamental a part of Fairy Tail to remove it. At that point you could just as well stop saying this site is a non-canon Fairy Tail and just call it some magic based RP forum or another.
