Overpower vs Steel Cyclone

[FallenWings]

The skills have different threat multipliers. Overpower uses a x4 multiplier, so threat = damage x 4. Steel Cyclone sadly is on a x1 multiplier, so while the damage is much higher, the resulting threat is lower. Defiance is a 50% threat boost with 25% damage reduce, so the total numbers look something like this:
OP = 120 pot * 0,75 * 4 * 1,5 = 540
SC = 200 pot * 1,5 = 300

* This is assuming that the Threat tables at http://valk.dancing-mad.com/tables/enmity-tables/ are accurate

That was Steel cyclone pre 2.1 when it didn't even have an emnity multiplier, hence x1.

Post 2.1 it gained an Enmity modifier. I've used it several times as an AoE snap aggro and it has worked spectacularly. I'm not sure on its exact number but from experience, it's almost like applying Butchers Block to everything you hit.

Infuriate, Steel Cyclone, Overpower x2. Enmity is now a non-issue.
