I would add that on the second boss Anub’zekt when he put the safe spot down on the ground the affix orbs spawned and how are we supposed to collect them? The boss was on one side of the circle so the only way to intercept them was to blow an immunity to quickly grab them.
I saw people stating concerns about how this affix would interact with certain abilities and lo and behold a day later I got a first hand experience of what they were talking about.
Assuming the same thing could happen on other fights such as the final boss of Grim Batol.
