"Sepparate" Unique items into 2 types: leveling or endgame.

Leveling should have a required level under 10 (or 20 at most for the most "broken" leveling items).
Endgame type should be endgame viable, simple as that.

I remember prophecy league kinda solved (not completely) this problem back in poe1..... It's so sad seeing "unique" (aka legendary in my book) being instant trash, because of loot filter sometimes i don't even bother identifying because i know it sucks, just straight up disenchant for the chance chard.

How to do that? Weapons should have way better stats, other uniques either more stats or game changing properties.
Maybe bring back "prophecy league like" mechanics that let us upgrade unique items so they become endgame viable.
