I just spotted this thread
on the Aggramar forums and you sound like just what i'm looking for.
I'm 30 years old and am married with 2 kids so i usually log on after 9.00pm when the kids are asleep for a few battlegrounds and the occasional instance. My character is a 70 UD Rogue who loves to PvP and have also played 2v2 arena. I don't take anything too seriously though and have no ambitions to raid at all. I'm very much casual these days.
I'm generally looking for a bunch of like minded folks to group up with and hopefully join in with some arena teams.
