We've seen Sastasha HM, we've seen Brayflox HM. Tam Tara, Copperbell, Halatali, Haukke Manor, Qarn, Stone Vigil, even a new Amdapor type dungeon. Am I the only person who wants to see Toto-Rak, Cutter's Cry, Dzemael Darkhold, and Aurum Vale given hard modes too?
Edit: confirmed in Patch 2.5, Amdapor Keep HM, Wanderer's Palace HM, and Keeper of the Lake... can we please keep recycling the nostalgic dungeons too?
