I had an interesting bug happen, I have been holding on to a bunch of +4/+5 enchants for a while, finally found an enchanting table and threw the enchants on my gear but they all came out +1. Admittedly it could be bugged base gear as the leather pants have 46 base, the necklace has 56, the fishnet boots have 18 the mace and sword have 123 and 96, my armbands have 21 but came with fireball on them already.
I know you mentioned working on gear balancing so I thought this would be good to know if those numbers are not supposed to be so high on some pieces.
Most of this gear and enchants was found from stores in the wild and some locked chests.
