I've been playing in official Kahrun for a while using BP. Well,there's a trick to get free 7 days of validation so the game's not really that vexing.
In case you're unable to use BP, WTFast would suffice.
But about one or two months ago, we, I and my other teammates, quitted since NCSoft's making AION into a easy-farming game and no real PVP at all. You would imagine this an ideal game since PVP is encouraged for both sides and the death penalty is not a problem either. But somehow the safe farming zones expand with the 3.5 patch and there's no reason why people should PVP when they can safely grind for AP...
The two new dungeons look really intriguing and, indeed, kind of hard but once we explored and got our hands on new gears, it's a let-down.
Besides, we was kind of tired from managing our guild's activities from raiding bosses, doing new guild quests to distributing loots and benefits. We found quite a fair system for all the members so it increased our work loads and all.
