Burden of proof lies on the one making a statement. In this case, the OP has failed to provide any sort of evidence of his claims. As Michael points out, it's perfectly fine to have an opinion, but it's hard to argue them... So until a claim backed by some form of evidence other than opinion is made, a debate cannot be held.
My statement: Mystic Adept characters can be created under the current Hot-Fix rules. Care to argue that particular fact, considering I make no claim as to whether or not they are "good" since that is a subjective opinion and not objective proof? No? Good...
OPs statement: Mystic Adepts are nearly-unplayable.
My counter-statement: Prove it, objectively, and not by providing subjective opinion. Yes, they cannot take 6 Power Points without taking a Negative Quality (or several). And?
