I found WoW to be, I think, the best game that I've ever played. Leveling up from 1-70 was both rewarding and fun, even if you're only playing a few hours per week.
Things change however once you hit 70, there are fewer single player quests, so you really have to find extra time to complete group quests (time to find a group plus time to complete the group quest). Then there is raiding, unless you can allocate a blocks of time between, normally, 6pm-10pm then you're not going to join a guild and you're not going to go raiding.
I quit WoW a few weeks after I hit 70. I might go back when the new expansion is released.
