Mistmoore Revamp? You mean you added 4 items and called it good?
Pathetic.

The problem is when a handful of options are so far ahead of everything else that the rest of the game stops mattering. If the correct answers are already obvious, why would I sit there theorycrafting or trying weird combos? There's nothing to figure out.
Being overpowered is fun when a bunch of different builds can get you there in their own way. It stops being fun when four or five combos invalidate everything else, because now you're not really choosing anything. You either run one of the broken setups or you knowingly play worse on purpose.
If the idea is thousands of possible combinations, but only a few are worth using, then the idea is only a gimmick for marketing. A balance pass wouldn't make anybody weak or take the fun out of it. It would just mean more of the game is actually worth playing, and people would have a reason to experiment instead of copying whatever the top META build is. This takes us right back to how WOW is balanced with the flavor of the month gaming.
Blizzard never gets that idea.
If the boss has to go invincible while they can still hurt you. That's just extremely poor design and low effort.
