one idea i have is that you add a feature that lets the player pick from the past UI's and chose the one that they like best (is the least confusing, best fit for them)
i personally dont like the new ui, BUT it did (intentionally or unintentionally) bring back upgradeable resistance drainers (they will do 1 damage per level that they are upgraded, damage is affected by resistance values, damage is also only physical, no matter what type of drainer)
