well, my "free" time ran out and i havent resubscribed, heres why: lack of things to do! i have several friends who have more free time than i do in the day who have been 40 for a while, and they have also given up, intending to go back once there are more 40s.
i'm not saying the games bad because its not, there just isnt enough there for me to want to continue playing (well, more paying). im level 31, and maybe i;ll go back to it someday, when its a bit busier!
for now though, i am back to WoW for the odd hour of gameplay, or on day of defeat.
