Considering how similar it felt to the Final Fantasy XI battle system (minus the macros), I can't see myself having problems with this system. It seemed rather intuitive to me in the demo, although that's probably because its similarities to a system I'm already used to. Either way, I'm sure it'll work out well. The only people I hear complaining about the battle system are those who haven't played the game yet, so that's got to say something. Granted, I can't say that I've looked around for many opinions.
