I have 4 80's in Wow and since I have started Aion I dont get back to Wow often.
The game is still a baby and there are glitches, however, the positives definitely out weight the negatives.
Gameplay is great.
PVP is there
PVE is there
Plenty to do at all times. I have two toons and between questing, instances, crafting and just exploring there is not enough time.
The PVP will be straightened out. Right now today NA servers went down at 12 am and will be down to 12 pm.
Also, though in LFG in this game instead of Trade channel in Wow sometimes lots of chatter but not like the chatter on Wow.
This to me is a good game.
Technically have not had really any problmes.
I am having a lot of fun but then where else could have all the above in one game.
Leveling is not easy, harder than Wow.
Would say Aion is a cross breed. Some FFXI style, some Wow style, some of it's very own original style.
I dont have many negatives because the game is so new. Things will unfold bettter and better. Why would they not want to improve on a major investment.
Seems to be a lot of Wow or ex Wow players in Aion.
