BC. Did Sunwell. Started a DK when wotlk came out but stopped at level 60.
your going to be VERY disappointed LOL Sunwell was easily the best and most challenging raid blizzard has ever put out.(AQ40 was nutty as well but was a little to long IMO) I remember people saying BC killed raiding but the raids could still be VERY hard like Kael, Vashj, archy, council, sunwell, hell even kara was hard at BC release. Wotlk is a complete joke for raiding...if you were able to do sunwell your gonna laff your ass off at the difficulty of the new raids, tho I will admit ulduar was awesome but thats ONE RAID.
