I am currently running CM10 on my HTC One S. The main problem that I have noticed is the battery drain that my phone has with CM10 Stable.
I quit playing World of Warcraft out of sheer boredom for the game. The game has become to easy in general to play End Game content. But I guess at some point every game has a point where it starts to become exceedingly repetitive or has been made far to easy to play. I haven't personally switched to another game in place of WoW.
