Dual strike build question

Basically I am at an impasse, I dont know whether or not to spend my next 10 passives to get that deadly precision on the one handed tree, or if i should just go for the damage passives I am already at.

Im only at about 17% crit rate atm, would be nice to have more


Im running a dual strike build with swords.
