It seems really cool to me that the DKs get to keep their Class hall. It is a floating base, and they've moved it closer to the action. Lore wise it makes perfect sense, and from a character build-up perspective it does too.
Only thing they should/could do is update some of the textures and possibly add access to a new floor in the necropolis. Remember nothing is finished product just yet, many models are currently still placeholders.
