I just hit 80 yesterday...It's my first and ONLY character, so it's really exciting for me. I enjoy not having to do quests to gain experience anymore (now it's just get money for that epic flyer, heh).
Anyways, my guild starts 25 mans soon, and I want to start running heroics to get geared for optimal DPS. I'll more than likely be raiding frostfire build at that time, but right now I'm still enjoying frost and it's what I'll use to run heroics until we start raiding. Here's an armory link for my character. I have no clue where to go and what to look for. If anyone can start by giving me a few tips and select pieces to aim for, I'd really appreciate it! Thanks!
