@b214 you're idea seems to be the most logical way for it to work (Issei losing the ability to use his hax moves), and now that I'm thinking of it a bit more it seems logical that he couldn't use Triaina or CCQ in a rating game as there has already been discussion of it breaking the game anyways. Plus by the time this were to happen (since one of his dreams is to make Rias king of the game) he would probably be to OP'd anyways. Actually I'm kinda hoping that would happen. It would be nice to see him win some fights without having to go BB and fight his opponents with his regular sacred gear like Cao Cao or Sairaorg.
