You arent claiming that AC == seperate class instead you are the one making the claim that AC's == same class, so you do need to provide evidence that hasn't been debunked for it, as all evidence you and others have provided has been debunked by others in the same fashion that you say you have debunked the reasons provided for the case that AC == seperate classes. So unless you accept, as I believe others have, that the debunking that has gone on both sides is not objective and does not instantly invalidate the reasons given. So we have to judge based on which provides the better evidence. As far as I can tell your arguments are that they share the same class story arc's and that they share a small amount of base abilities, which is hardly compelling at all.
