The problem is that most players need to feel as they are amazing not be shown they are terrible. I myself find WoW boring if i stick with 1 class / spec for the expansion so i have to change it up every single season but what i do not do is want to be a gatekeeper on content either. Cataclysm heroics were terrible but what blizzard should have done is have a competing end game progression system akin to M+ to take away from the raiding pool for end game activities to force them into a more niche audience like it is now so you can have set standards for what people are willing to do and since people really care about 6-10 item levels on a few pieces its why raiding as blossomed into the premier end game activity.
