the map rerolling in the void needs to be removed.
the map reroll is a bad design aspect of this uber, as i said it before the idea is beautiful but in practice its annoying, you spend 3/4++ of the time on this uber on map rerolling so i want to bring it back into your consciousness
as for related feedback: today i spent 2 hours 30 on rerolling and didnt get a new scroll (needed 2 more for ring), but the rolls were many times the boss room and the POINTLESS ROOM that gives you nothing directly related to finishing the uber, so a lot of time wasted for absolutelly nothing. and in this case its 100% true "its not even hard, its just annoying"
you know what would be another acceptable compromise (the other suggestion was multiwarp in the void map itself)? since a lot more warps can be made you could try to put multiple entrances into upper kurast, perhaps 3 or 4 that lead to the different maps but you get everything in 1 game every time. they would still be in random posiiton so there is some rng, but the amount of time wasting of remaking games which is my main point of criticism would be under control
