Is World of Warcraft for me?

I'm a gamer. In the past I've played Black Ops and MW2 for hours and hours a day but lately I've been playing more RPGs and offline games like Fable, Fallout, Oblivion, and other stuff like that. I still want to play online but in a different environment (No head shots, quick scopes, noobs, or drop shots). I was thinking World of Warcraft or another similar MMORPG would be fun. Tell me what you think.
