I think there should be some changes made to the Death Knights main floating base.
There doesn't seem much point to having an upstairs and downstairs these days.
How would you redesign this place, and what would you like to see?
Rune forging should be upstairs, I think.
In addition to training dummies, I think it would be cool if they still had those chained up misfits/rejects to duel at whatever level we want them to be.
Maybe we could duel the masters of each spec that are hanging out upstairs.
