1.9 is not a content update. Making some quests repeatable does not mean content. There are still tons of bugs unsolved from version 1.5, not to mention the new ones from 1.9. Balance ? Let me laugh about that. Look at how unbalanced are the servers even after the merge.
Why do the Aion fanboys always talk about WOW ? That was a pioneer in the MMO field. Why do you not mention the other 3 or 4 MMOs launched at the same time with Aion, who all already got 1 or even 2 updates in the last 12 months. From the pack of MMOs launched in autumn 2009 , Aion is still the worst at updates and support.
