When using Best in Bags, i often find that i’m not going to enchant a low-level item, but i want to enchant a max level item, so i leave the Epic Gems & All Enchants on.
But when i get a new Azerite piece the % upgrade gets lost in the 2-4 % difference the enchants make.
So my suggestion is that you make the +% DPS/HPS/TUF without any enchantments and gems and in smaller font below of off to the right of that larger % change, you show it with any Ench&Gem changes.
Similar to how your “Effective iLvl” in-game is different from your currently equipped ILvl
