Endgame is not rewarding at all

True, my last upgrade was 40 levels ago... I'm 90 and my last upgrade was lvl 50... I'm doing t16s and citadels on a 4links with stuff I found during the acts weeks ago.

I got 10 divs tho. Despite using all my currency, nothing works. I never had this issue in poe 1. Poe2 item aquisition is legit the worst I've ever seen in any arpg
