And rightly so, I actually quit WoW 2 months after release and re-sub'd a little bit before BC. WoW's release was horrible, un-playable and just not fun for me. BC was enjoyable but only because of friends in the guild, towards the end WotLK it started to feel like a 2nd job with all the b.s. elitest bs and I un-subbed again.
I have gotten more "entertainment" out of TOR for the past month then I did with WoW and for me that's a huge plus.
