well it shouldn't matter what materials i put into the utility, offense, defense slots as long as i put tier 4 material in the damage slot, right?
Counter-argument: why shouldn't Attack% increase DPS? I realize none of the builds above actually have Attack%, so that can't explain why the DPS is higher, but I don't see how a buff for Attack% would fail to increase DPS. It increases actual damage/second, that's for sure.
And if that's true, then Dex buffs should also increase DPS, since Dex on a rogue increase Attack%.
And if that's true, then Crit buffs, for chance or damage, should increase DPS, since crit bonuses increase average damage/second. And since Dex increases crit damage, that goes double for Dex.
And if that's true, Cun buffs should also increase DPS, since Cun increases crit chance.
But I admit I haven't actually tried crafting different combinations to see what really affects DPS, since DPS is a pretty worthless metric to begin with. Be excited about a base damage 191 dagger, not a 500+ DPS dagger.
