I feel the same with WAR. It's missing something. Levels 19-21 were just, ugh. The game just isn't drawing me in with the lack of community(chat channels), the gear is boring, and pve/world almost has a linear feel to it. I already got my reminder that my account(free month) is up but I don't think i'm renewing.
On the flipside, pvp is a blast but it goes back to how many time can I do a scenerio before getting bored.
Not sure I could or want to go back to playing warcraft though. Its just too much of a time sink. I am how ever curious if pvp is getting better.
