I think that loot listed from Ivory might be guaranteed for at least 1 person, since I soloed like 3/5ths of a LoD (other person left after the 2nd dragon) a few days ago and also got 1 def, 1 dex, 1 draconis potion, and the mark.
I don’t really think 1 def and 1 dex for doing potentially the entire dungeon solo is quite worth the squeeze.
(also related: I feel like midgame dungeons such as these, which are feasible to do solo but take a long time, should reward more for a solo at least. Ideally, you’d have a group of people to do the dungeon with, as is expected for an MMO, but from experience, people get bored and it won’t be as good of loot as just doing glands dungeons or, in USS nexus case, waiting for the next pop with lots more people, in that same amount of time, so people just leave and then you’re left alone with the option to also nexus or finish the dungeon.
Also also also soloing means you get to see all the phases of a boss/most of what a dungeon has to offer as nothing will get steamrolled or skipped, it’s fun and a neat experience and adds back some challenge to dungeons you normally sleepwalk through in groups and we really should reward this)
