Why Do Mana Users Have To Manage Their Resource?

[Krotoan]

I'm curious as to how you AOE as a DRG. Nobody ever uses Goad on me, and I can only use Invigorate so often...

There are very few places I've found that you can completely run out of TP before the end of all the available enemies. Weaving jumps and building to nastrond also helps not drain as fast as just the 2 AOE skill alone will.Once you get down to a few enemies you really should swap to single targeted damage. And even if you DO run out of TP it only takes a few seconds to refill.
