Well, you can't just say that 1% MC is X or Y DPS. You have to calculate each parse for itself. I might be wrong, though.
If you want to do it, check Ranger forum for the formulas etc.
EDIT:
Okey, I calculated how much DPS I gained from 1% DA and 1% MC. I used the parse that I posted in 'Parse thread'.
1% DA = 22 DPS
1% MC = 28 DPS
+50 CA = 38 DPS
However, MC is lower than it actually is. I didn't use Pirate Stab, Interuppt and Counterattack (they crit on MC) in the calculation.
I don't have them in the calculation because I am not sure if they have the same ratio as CA damage.
EDIT2:
Okey, calculated +CA Damage, not sure if it's wrong
And, no problem ;)
