Quote:Impale itself is only ever a small fraction of damage, say you have 25% crit and your meters show your damage at 50% white damage and 50% yellow damage... Impale is 0.25 * 0.5 * 0.1 = .0125 or +1.25%
Small nit on your equation. 25% chance to crit does not mean that 25% of your damage will be from crits.
To give an example, if you have a 25% chance to crit, and your average damage per swing is 100, and 200 on a crit, 4 swings will on average produce 3 hits and 1 crit, which will come out on average to 500 damage, of which 200 damage came from a crit, which is greater then 25% (in fact, 200/500 is 40%).
Impale makes that math a bit more tricky, since your crits in the above example will do 220 damage, but it's still easy enough to calculate - crits will provide 220 out of total 520 damage, or 42.3% damage. The percent damage of a crit that comes from impale in this case is 20/220 = 9.1%
So, with 25% chance to crit, assuming 50% of your damage is yellow, impale will provide...
0.423*0.50*0.091= 1.92% of total damage, or roughly 1% increase in damage per talent point. This percentage goes up with increase in crit rate, of course.
As for the original post...
Ironically, while most people say they go for Impale, from my experience and parsing, it's usually the Deep Wounds that provide larger DPS increase, ranging from 3-4% for dual-wielding Fury warriors, to 5-7% for two-hander users.
Of course, as others pointed out, DW spec will still give you higher increase in damage, however there is no reason not to have both if you are aiming for pure raiding (thus not really requiring extra points in Improved Intercept and such).
Another thing that I noticed is people's choice of Improved Berserker Rage over Anger Management in their PvE DPS builds (not saying that this is directed at you Lok, because some people do enjoy Fury in PvP! :)). While the first one provides 20 rage over 1 minute for 2 points, and eats 2 global cooldowns, Anger Management provides 30 rage over the same minute, passively. 30 rage is another Bloodthirst every minute, which is a lot.
