The split was caused by people having to rely on external websites to match up to complete end-game activities. Those sites let people be elite douches and try to rush the objective, by setting certain requirements, thereby excluding certain players who hadn't recieved Gally from RNGesus. The problem here isn't the weapon being OP, the problem is people weren't given a matchmakimg option to eliminate this elitist mentality of "it's my rules and you better have <blah blah> or else you don't get to play."
