Mourndale - please put a riftgate at Daila’s location. Mourndale/outskirts is huge, it houses 2 dungeons (which are ass-backwards for the purpose of Daila’s quest), it also houses secret quest and that one shrine you need Aethersteel bolts/trip to blacksmith for. Clearing through it all in one go is annoying every single time, and requires either dropping personal riftgate at Daila’s or walking backwards an asinine distance each time you forget. Give her a riftgate proper, there’s no reason Mourndale/outskirts can’t be split in half. It’s huge enough for that.
Undergrowth - a long time ago there was a pass made on vanilla dungeons, to give them all an exit at the end. The effort missed pretty much all AoM dungeons. Most of them are short enough for that to not be an issue. Undergrowth is not short. It requires annoying amount of just walking back from the boss through a cleared area. There’s no effective way to portal out either. Please put an exit there.
The other you quest - can it please become available once you enter the Crown hill, and not the final dungeon? As it stands now, you need to get into Infestation, portal out, walk through the awkward geometry of Coven refuge towards the questgiver, then walk back the same awkward distance to the portal and back into Infestaion. Again, it’s annoying and takes longer than it should just because of the weird quest availability trigger.
Bonus mention - move Barrowholm riftgate closer to Barrowholm proper. I don’t know where.
