Revert the Chalice of Harmony HARD gutting
Chalice of Harmony since S1 was historically an item dedicated for hard-mana users but for some reason, in late S6 it was gutted to remove the mana regen passive and instead replaced it with a horribly misplaced HP regen passive.
Now maybe I'm seriously missing something, but what was the point of gutting/removing the best mana regen item the game?
