I'm just putzing around on some old characters, with no intention of playing seriously again, but I'm trying to wrap my head around the level squish and Chromie Time. I left off in BFA, raid-geared but early tier. My toons are all lvl 45. Azerite gear still works, but Legion legendaries and Artifacts don't.
If I switch to Chromie mode to level in Legion content, will my Artifacts from Legion work again? Or will my azerite gear stop working? Can we bounce around playing with all the different xpac toys simultaneously? Or do they all go cold equally?
