It's REALLY hard to mess up a party system lol
I can't even think of a game that screwed this up...maybe KZ3 with its "wait...am I in this party?" flub...even THAT didn't take much getting used to
I am confident in everyone's party system.
I agree with you that the R1-L1 can be annoying at times when it comes to switching gods, however i dont think it'll be that way in the final game, i really dont want to have a choice to keep on switching between gods, i think that once you pick and pledge your alligence with one god, you shouldnt be able to switch. Though if they do allow that, I dont think they should change the buttons, because you'll be able to switch back and as long as you keep an eye on the screen you'll be good
