Looking for a low key MMO

Durray

Hey everyone I really hope you can help me.

Recently I stopped my Aion subscription I just don't have the time anymore to play it. But I would still like to play an MMO (preferably fantasy, pve and pvp, dont mind open world or instanced, with good enough content) but more casually. Just for a couple of months to fill in the gap until GW2 comes out. Hence though I like grinding games (i played aion for 16 months!) something a bit tamer would be great! 

I am not going to play Rift.

But I had heard ok things about WaR and Lotro and since its just a filler game I don't playing some old games. Graphics aren't key.

Thank you in advance.
