This means you now have legacy items
Uniques in POE are supposed to be UNIQUE, not better, fluffed up and fancy rares. Some are just fluffed up rares, yes, and others are simply leveling items, but the majority have UNIQUE modifiers on them that cannot be gained anywhere else in the game, and as such can be build enabling. What you're thinking of is something along the lines of Legendaries from other games, which are the super GG items that have no better equivalent and are very rare.
For future reference, any characters in temporary leagues will be returned to their parent leagues, regardless of whether or not the game-play mechanics are being transferred to the core game. However, any League Specific items that you have in your stash/characters will also be transferred to standard, once again regardless of if the mechanics are going to the core game. This means you now have LEGACY items.

poe4orbs:POE 3.17 Siege of the Atlas Official Trailer
Really think the new atlas skill tree is going to be a success, personally i've played PoE for a long time myself, and looking just slightly on this, i really think it just looks fearsome yet it looks really nice developed so newer players can easily look where they want to target farm. Especially comparing it to the old version where a lot off new players never even got to the point to actually start target grinding, well done!

PoE 3.3 Gladiator/Slayer Sunder Build | Crushing Maps
I have learned a lot from the top ladder sunder pushers, so I am going to create my own Gladiator/Slayer Sunder Build for the new PoE 3.3 patch, I think my build would be useful and resilient in Incursion league. And if you are new to PoE, this build could be also a good starter build for you.
