My only issue with this new legendary setup is if I remember correctly Blizzard wanted it to take the entire expansion to acquire it. If it does indeed take the entire expansion then there will be such little use of it making it feel pretty much a waste of time. I'd much rather have stuff to do similar to the Shadowmourne quests. I don't prefer it to be back in vanilla/tbc but I also don't want it in it's current state.
