What could valve do besides skins?

I come from tf2 and overwatch background and one thing i hate from both those games is the escalation of ridiculous skins.

It ruins character silhouettes and recognisability imo.

So, what else could valve introduce?

Something like csgo knifes, the good thing about cs knives is that they don’t change anything in terms of visuals in the game in a way it obstructs the game.

Like 10 years down the line if there are a o of cosmetical effects or skins and u dont recognize em, it will make it harder to understand what or who you’re fighting etc.
