Brother, you know how much everyone seems to love Second Wind? A Mega-Potion is a second Second Wind avaiable with basically the same cooldown, it's damn helpful. And good god, I've been on an Aurum Vale run yesterday (my entire team's first ) and good god, i'd so have LOVED for my team to have a mega-potion to save itself when they HP were in the last 200 and I needed just a HALF SECOND to cast that god-forsaken cure.
