I would have to say Guild Wars 2 is one of the easier ones i've played in a while.

Checkout neverwinter, It's from D&D Creators and it's Extremely fun and Free! if not checkout Dota 2 on steam haha it's even better

Depends on what u mean really ? If this is your first mmo then i'm not sure. I played Fiesta Online (ftp but cheap and gay graphics) it's a half decent one to start out with. And WoW also if you don't mind the subscription fee. Personally i quit wow do to me doing the same gaming routine day after day. I've heard Neverwinter is good, and i like the look Rift, and i'm about to try LoL and Dota2, which i've heard from different people are both good. Personally i'd recommend all of these games mate! So give one a try :-), (fiesta doesnt require a good pc and is a small download).
