Don't have much experience vanilla since I didn't start during that time, so I only do some of those raids to try and get mounts. BC I full cleared Kara, ZA, and Gruul's Lair, helped with certain bosses on TK with you guys, and did Mount Hyjal with you guys all the way up until the last boss. In LK I've pretty much full cleared everything Except Ulduar(I wasn't around during that time) and ICC, though I am knowledgeable on all fights and have cleared 10/12 on 10man.
