Huh... I didn't really have these mana issues. Like, I'd pop LD at around 6.5k mana and I'd reach back up to around 8-9k just fine. Of course there were diminishing returns each time it was used, but I seldom saw myself get below the 5k mana mark before the fight was over.

The only troubles I get is when I have to play Rezz Mage to pick up 2 healers and a tank. *laughs awkwardly in Eden 3 flashbacks*
