My thoughts on the changes to things like UP are the same vein as yours with Devourer. Once you've done it, it just becomes a timesink. I don't enjoy engaging Sorrowgrave or Shadowseeker, having her on the ground for 5 seconds, up in the air for 15 or whatever, down for 2 up for 15.... especially when my team is mostly melee-range. Nor do I enjoy having to deal with waiting on Skadi {and deal with an extra wave of adds} if I just needed to launch one more harpoon to down him.

It just gets tedious after a while. It doesn't add anything to the challenge, it's just stuff that forces me to sit around and wait.
