I am most looking forward to the upcoming changes to Hunters. It's kinda amazing how different each spec will be, and I'm hopeful this will be a template for some future options on other classes. Joining my current (and second overall.) raid team in the middle of Firelands was my best moment of WoW past. I had filled in every now and then when someone was sick or couldn't make it due to work or other RL stuff. And when someone bowed out indefinitely they asked me to officially join the team. It was so great and I'm still loving all (well most ) of our raid nights
