I understand needing to grind in order to unlock various bs gimmicks that come with the game, what's the point of credits if I can't use them? And why do the devs think it's a great idea to not have an overall level and just have levels for the classes, I started today and I've gone up against full squads with maxed star cards, what am I supposed to do at that point? They gave more health, more shields, better throwables it is David vs goliath, but goliath wins.
