but i think the biggest game breaker for newplayers is the combination of: DCing quite often, loading screen hang up to for several minutes, plus sometimes needing 2-3 attempts to log back and return to the game. This with fairly common lag scenarios, eg: certain quest completions, mass spawns..
The first thing they should solve is better stability of the client, and loading between areas without DC. Without these critical bugs fixed, it is hard to recommend the game to anyone.
They could also remove/or just move the UI store accident buttons, they got me a few times with them, and i am sure this adds more to the annoyance than marketing efficiency. (Seriously who makes these decisions? I didnt know that a business pays salary for griefing customers.)
