Well, I mean, you COULD activate them from inside dungeons, but it would teleport you to the entrance or the nearest town or something, and THEN you'd have to find it on the map and teleport to THAT... having it a bit streamlined would be nice, aye.
Unless nightmare dungeons give you more Obducite than a 10 wave Infernal Horde, then they are still not worth the hassle and time.
Wish they also add some indication when you have a sigil for the certain Tree Whisper dungeon - always liked to combine the farm with collecting the grim favors.
the less loading screens the better seeing how they still dont know how to fix the black screen &*!@
