This was a really crappy update for Aion full of level grinding and unbalanced skills.
I have been away from Aion for exactly 2 months now, and I am now ready to update my review for 2.0 and 2.1. The initial release of 2.0 contained many difficult to obtain eternal and overpowered armor and weapons, but 2.1 updated the game to easy-to-obtain drop-rates and a more user friendly xp gain system. Since NcSoft allowed the trade of eternal weapons and armor, they made it clear that they condoned the trade of eternal gear and that they wanted the majority of players to have said gear. As for pvp, the side that dominated (usually elyos) had the upper hand on getting the most ap.
Seeing as I have already writen a review on Aion, the only issues for 2.0 that needs to be addressed are pvp and Stormwing Hard Mode runs. HM Stormwing runs consist of a 1.5 to 2 hour rush through Beshmundir temple which was quite easy with a skilled healer. You get various pieces of gear which are worth 30 to 50m and are sellable. A group with full pvp gear can easily do a Besh HM run with little difficulty. The armor piece drop rates are completely random but seem to favor chain wearing classes. A gladiator can easily be used to tank Besh HM.
As for pvp, the game is pretty much the same. Templars were given a slight more damage and the same amount more defense. Gladiators were given another AOE but still somewhat lack in burst dmg. Sorc's are still the highest dmg. class in the game but somehow the majority of them are still sub-par players.
Aions major issues are with the core game values and characteristics. There is no pvp vexing system based on how many people are involved in the kill and the value of the kill. You lose the same reguadless of who or how many people kill you. The new skills didn't really do anything to balance the game so the majority of classes didn't have any new skillsets.
Even if Aion included a whole new pve and pvp system, the game would be crap. Honestly the game has gotten worse from launch.
