I feel like Judgement Day is a hell of a lot less fun than it used to be in the Cloister?
Whether intentional or not, being able to kite the edyrem into the Jail leaving only Uldyssian made getting both Malthael and Imperius not too much of a chore, but I find nowadays it's awfully tedious. I have spent many hours this season getting to Izual, killing him, going through Khalimgrad to open the Diamond Gates, kiting all the edyrem away, spamming edyrem on top of Uldyssian and just waiting for RNG to be on my side.
If one of them spawns and you don't kill them quick enough, you then have to try and kite the extra edyrem that have spawned so you are back to only Uldy and repeat. Eventually, if you are unlucky (which I have been nothing but so far), it becomes such a hassle to split up all the extra edyrem that I have to save and quit and go through the process of getting back to the uber again.
Maybe it's just me, but waiting for complete RNG for potentially hours is incredibly unenjoyable compared to any other uber in the game.
