Steam Achivments and the support of them

I just wanted to say I really want them to be supported more in POE2 fun challenge-based achievements, grindy one and ones that can be creatively made to make the players play in a way they never would. I think of challenge runs tied to achievements and the dream would be cosmetics tied to hard and grindy achievements, but that will prob never happen. Would be cool though think of halo 3 some gear if you saw a guy with you knew he was either good at the game or completed a challange then you could tie upgrades to the armor (visual only) you could charge for like animations, floating, flames etc. so you make money off of them and you accomplish a challange.
