do many people xp lock at 30 to raid all the older raid stuff like icc/naxx/uldaar? Are dungeon mech as a lower level working properly in retail? i was trying to clear all the wrath dungeons and there is that one where lich king chases ya and proudmoore up a tunnel but it bugs out on my 80, i was thinking of making a 30 to do this dungeon and just wondering if it works at lower levels
