Tell you what though, I completely agree with you on T4. That fight was fun as hell to tackle during 2.0~2.1, because of how well everyone had to be on point to ensure success. Essentially it became a fight where gear did not matter at all outside of a simple DPS check. Now you can simply faceroll it with gear and obtain easy reward.

That's kinda the trick though, isn't it? There's no mechanics you Absolutely Must deal with, so the mechanics that do exist can be increasingly ignored as gear and general power continue to increase, and slowly the fight will lose identity, and ultimately challenge.
