What if... Black and White Mana DO NOT reset upon Map change? Embolden should be used right after enchanted Redoublement into Holy/Flare, so to maximize DPS you want to get it as stacked with the other opener DPS buffs as possible... So you'd want to enter with 99/100 mana. Imagine flubbing that first pull and losing all of your black and white mana and having to requeue.

God SE. SAVE US FROM OUR MIN/MAX SELVES. PLEASE TELL ME BLACK AND WHITE MANA WILL RESET TO 0, UPON MAP CHANGE.
