I have no issues with there being a instant gear mini patch at the end of an expansions content cycle. Progression is over there isn't a really a point and if im being brutally honest I doubt people care about clearing mythic after the shadowlands prepatch.
My problem is when these weird systems become a part of progression. I don't think people examine how bizarre wow's current systems are in a vacuum. In any other game if your on the last level fighting the most powerful enemies you wouldn't expect to be asked to go back to the first level and fight the easiest enemies to gain some weird reputation that only they gave.
It is jarring and it breaks the pacing. I would honestly like to see every system that awarded daily or even weekly power removed. No Ap, essences, conduits, soulbinds, renowned, soul ash, or any other system they tossed into the game to cheapen it and draw out content.
That isn't even talking about the harm these systems do to the game itself when they try to make them expansion features... Remember all the lore Throne of Thunder had? If you didn't do it in MoP you won't since they ripped out all of the dialogue when they removed the cap quest. WoD I haven't checked on but I don't think you can get the ring anymore so you lose out on those quests as well.
I left myself get off topic but any kind of weekly grind item that isn't simply cosmetic or at worst a crafting pattern for a boe item really would be better of not being in the game.

I think your taking this to personally. I don't really care about what people have I am speaking about the system itself.
If there was a game system that made it so if you ask the town guard where to go to learn blacksmithing thirty thousand times in a row he would give you your bis legendary I wouldn't disparage people for doing it but I would bitch and moan about how such a system was allowed into the game.
