Jan 26th 2010 12:54AM Yes, you have to manage your energy, while mana users get to essentially ignore their resource until it's almost gone. However, mana users only ignore their resource until it's almost gone if they're REALLY REALLY BAD.
You manage your energy, and 5 minutes in your'e still pushing the same dps as you were from the start, albeit waiting for cooldowns. Mana users? Even if they manage their mana perfectly, eventually they are going to end up with no mana, no mana restoration cooldowns, and lose. The question of winning is whoever this happens to first.
So yes, mana users COULD just ignore their resource and spam heals on their team. But they would lose. Managing mana is infinitely harder then managing energy or rage.
