With wow... there is so much to do, but w/e it is you choose to do, pvp, pve, make money... you can't half ass it to be as good as you want to be. Either invest ass loads of time into it or dont do it at all...
I couldn't PvP cuz my gear sucked... didnt want to grind 1k honor per game cuz it was boring
I couldn't PvE as much as i wanted to therefore I had to play w/ retarded people, gear matches ur intellectuality i guess...
I COULD make ass loads of money, but like i said, it takes too much money
Aion is a new game, not many people do end game content as far as the US goes. Leveling is fun, especially once you figure out your class. There is some grinding you need to do in order to start questing at a desired level.. but its a minor set back.
I quit wow, i currently play Aion w/ a buddy and im having a blast.
