Locking in a party of 4 after Act 1 goes 100% contrary to almost everything I'm fighting for with this game. I'm calling for a party size increase and want the ability to switch in and out MORE party members, not be stuck with the same four for the rest of the game.
So, hopefully they won't do that. That would quickly turn this game from one of my favorites to the worst ever. I am ALL about characters, which is why I want a bigger party, not a limited one and locked out of switching them in and out.
