Ugh you're right can't believe I forgot space was dodge. I think 'E' is a better option than 'Q' it's easily accessible from 'WASD' and isn't close to anything else.
I did mean for every attack to face the mouse. When you use mouse buttons as controls it makes intuitive sense for the mouse position to be considered as part of the input and the behavior between normal and special attacks should be consistent. If you want to keep attacks relative to player facing it would make sense to abandon mouse attack altogether. At least that's my opinion but these aren't really the kind of games I make so don't feel the need to take me too seriously.
I've always meant to play Final Fantasy Tactics but never got around to it
