Server Stability, i felt some lag spikes in some popular maps, such as Glast Heim. Community are average, many people still prefer to go solo and leeching. GM are not very friendly. I hate when they immediately lock topic after they answered, like OP had no other further questions. But the good thing they always answering fast like 1~2 days, for me, that's fast enough. Since they love to lock topic after they answer regardless if we still had related stuff to ask, how that can be very helpful.
