Recube or keep?

I'll take your word for it that you have maxcritdmg of 240%. So your avgcritdmg now should be (2.4 + 1.3)/2 = 1.85x.

You gained 16% mincritdmg. Factoring that in, you basically have an average raw increase of .08x, or a DPS increase of .08/1.85 = 4.32%.

Say you have 165%DEX. Legendary %DEX potential will be 13%DEX (I think). If that 10%DEX stays intact, then it would have been 13%DEX into 175%DEX, or a 7.4% increase in DPS.
To go further, if in both cases you also have a Legendary 13%DEX, then the total %DEX to compare is 188%. Then 13%DEX would mean 6.9%DEX.

The breakpoint %DEX for a 13%DEX to be poorer than 16%mincritdmg is 8/0.0432 = 185%DEX.


Conclusion:

You either recube this, or recube something else.

I recubed and got 23% dex, which gives me a total of 182% dex, or 192% factoring in Xenon's link skill, thanks guys.

I have to wonder if a line of Decent Speed Infusion and a line of 13/10% dex would be better though.
