I use to play Aion, but you named my two major MMO's... GW2 and SWTOR. I play GW2 quite a bit on the Rp server, and I use to play SWTOR a good amount, but have grown away from it, for the most part these days, it is just GW2. 

I want The Elder Scrolls Online too though, I just won't have anything to play it on. Baha. Oh well, it is not a necessity.
