That design was because Raids were tuned around that gear just like 5 mans were tuned around certain gear and so was open world content. The gear was a means to an end which was seeing and beating the hardest content in the game. That’s all gone.
Now WOW is just a skinner box. Anyone just doing WQ’s, Islands and LF* instances doesn’t need the level of gear pouring out of the game right now but it sure feels good to get it. Gear is a drug and Blizzard is the dealer.
