At this time the game is suffering from at least below list.
-zoning and loading problems (slow or hang infinitely). You can only close game and reload.
-structural lag on weekends in europe. PvP is not even worth trying at this time.
-broken quests
-to much maintenance on prime time, just admit this game was not proper tested and rushed to market. Saturday 20:30 is not a maintenance window, so something went wrong again.
-dupe bug. The dupe was in there since launch, the devs knew and just ignored it. This basically gave the gold farmers millions. Bye player based economy.
I urge every one to enter tickets en keep entering them. Maybe this way they listen to the customers. if not I see most of the current player base dropping out within a few months. This game already doesn't have that much to offer to keep on playing.
