Would Duality working with combo effects be a bad idea?

[Sevyrr]

Yeah, at 966 crit total, you should be doing 1.6x damage with crits ... If you want crits that are twice the damage ... you would need something like 2,360 crit rating total.

... damn, that's insane.

Edit: I did the math, and the current max-crit setup for NIN would make Duality AC + 2x AE less than 18 expected potency above Duality AE + 2x AC. So if you have to sacrifice pretty much anything to set this up, like, say, losing a single dot tick, you're losing potency. And, of course, this assumes that Duality AC would actually give full +60 duration.

.... wow, I stand in awe.
At least it shows that, in theory, there would be a dps-gain. Irrelevant but to a parser, perhaps, but a gain nonetheless. A lot of people would go for that.

What resource did you use for the above information, by the way? I should perhaps familiarise myself with it to stop making such huge over-estimations in the future.
