hey, if someone else here gets to make a Phoenix Wright reference, then so do I
While your claim was indeed, different from what they argued, your counter-point has nothing to do with their argument. Your counter point was that you never argued about moves becoming characters. Or, at the very least, that was part of it. But they claimed that you shouldn't be using roles in past games, no matter how significant of insignificant they may be, to support your argument about characters being in future Smash Bros. games.
Also, this is just me adding to claims. I don't have very strong feelings on this argument.
