Can we just revert manaflow band to meditation and call it a day
I mean you don't need to be Isaac Newton to see why Manaflow Band is a badly designed rune. Personally I think Meditation was fine the way it was, I've never heard or seen a single person complain about it.
Manaflow band is always going to be either overtuned or barely noticeable now, and the really small but constant mana regen from meditation is better than waiting for a decent amount every 80 seconds(that's probably what they're going to nerf it to again).
