I agree on putting Duriel at the end of NM100. We need glyphs leveling and Duriel kills… hitting 2 birds with one stone. I dont care if Duriel is level 154.
Or put all Ubers on Vault NM dungeons. When Varshan is killed, it would unlock the door leading to Grigoire. When Grigoire is killed, it would unlock Lord Zir… and so on unlocking Beast in Ice then unlocking Duriel… and lastly, when all of them is dead, it unlocks the door towards Malphas. Also put stash, blacksmith and weapon vendor inside the dungeon every after Boss kills. All of these in one dungeon run.
