It sounds like you mostly run with precision based DPS. If you run with some heavy might based DPS (fire, elec, some nature builds), one of their full rotations will deplete about 3/4 of their power bar. I think two power dumps would be just about right to mitigate that power consumption. And like I said in the guide, I am assuming the reader has some knowledge of the game and roles. Using a power dump when everyone's power is full is like pouring juice into a cup that's already full, its basic knowledge that transcends even the game not to do that. Nothing is set in stone when playing our roles in DCUO, except for the fact that controllers should be frequently hitting their power dump when the party needs it. Many of the times, even before some of the revisions to the guide, when I said to spam the power dump I also said "when in battle" or "when the party needs it", this should be telling the reader that trolling is a very dynamic role that requires them to read each situation and alter their play style and rotations accordingly, as long as the basic requirement of giving power is being met.
