I have played on Icecrown a bit, got a Holy Paladin to level 80 and mostly done with heroic farming. Also been playing on Outlands the past couple weeks and just hit level 70 on my prot paladin. Names are "hijinked" on both servers, both Ally.
I have been loving the high population on these servers and I'm looking forward to doing a lot of PvE here.
I have been streaming some of my play time the past couple weeks on https://twitch.tv/hijinked if anyone wants to hang out. I'm going to try to stream from around 5-8pm a few nights a week when I can.
