Finally got around to some crunching. I doubt the arcana time investigation will change some relative values I came up with.
I know I made you put an activation time in Voltaic Sentinel, but Dynamo should be given an activation time of 0. Unlike Voltaic Sentinel, it is permanent. Ditto Cauterizing Aura, Hot Feet (possibly others).
Epic Pet damage is either incorrect, or the most damaging power in the game. Are spiderlings really 300 dps?
Pets aside, and surprising no one, Blaze is the most busted power in the game. It needs a slower casting time or casting time needs to start being accounted for in the damage formulas. It's absurd.
If you're going for ST damage above all else, it's Fire/Elec or bust.
