They increased the difficulty of the maps since soft launch. So not only did they take hero slots away from f2p players they also made it impossible to 3 star maps and progress through getting materials,hero shards, etc. It doesn't matter to soft launch players since they got the easy maps and have already 3 starred all of them and can just sweep them. Events will use soft launch players as a base for difficulty that are way stronger then new players so don't expect to be able to participate in them either. This game was literally killed on day one of global launch it's hilarious.
