The main reason for not allowing slayers as the first character for new characters is to dial down the overflow of Slayers on this fanon. If you're familiar with Naruto, think the sharingan and rinnegan. Everybody -- well, almost -- wants to use it with their character from the get go. And half of those characters turn out abandoned at times. Too many Dragonslayers, that's the deal with the limitation on Slayer character creation for new users.
