I’m in my first play through of Diablo 3 currently and I’m level 27. I have some OP rare items and they all regen my health so I can’t die. I’m wondering if keeping these on while I level up will stop my from getting better and better armor or weapons?

Like right have I have 33 rare armor pants but I have normal blue 76 armor ones. If I put on higher armor armor and weapons would I be getting higher level armor and weapons? Basically wondering if sticking with certain ones would hinder the loot
