This whining is so funny to me. And the OP hits the nail on the head, the argument of "let us overgear this" is really the only argument. There was significant imbalance between specs during Legion as well, yet people were fine with it because they could eventually overgear it. Like guardian was tuned to have to do a lot more than the other tank specs, and balance could breeze through what spriest and afflock had to struggle through. Almost all the dps specs that had to do the imp fight had much less to do than the the dps specs like arcane and demo. And the list goes on.
It isn't until Blizzard standardizes the gear and makes it actually about skill that people start complaining. Imagine if they had put the artifact skins back in the game. The forums would be on fire lol.
