@OP - I have to agree with HK-51. That is great advice.
I am also someone thinking about coming back myself. Right now I abhor WoW's PvP at the moment. People say TOR has a lot of CC and I will admit it has its fair share but in WoW CC is totally out of control. I actually preferred the PvP in TOR before and only feel moreso now.
Recently loaded up SWTOR and played a couple WZs and I had forgotten how much fun it was. I am going to be coming back but not sure to what capacity. I am really giving WoW till 5.2 to fix their crap if they don't I'm jumping ship and coming back to SWTOR.
