what's the reason?
Might be because of the overpopulated servers with 54-90 people in it at a time, and all the other ones have like 10 people being afk or just plain inactive on that server. The problem with overpopulated servers is that whenever you step out of the spawn your all like "Hey guys whats going on out he-" <insert explosion/backstab/flamethrower here> and you can't really gain any experience and just seems frustrating in general.
