Steady aim should practically be a mandatory passive.
I attack in exactly the same number of center hits [8], nothing to sides, only right attack
But my dps is only 18K sharpshooter.
The dex you get to sacrifice in exchange for much more MF & GF is absurd. It adds more damage by itself than sharpshooter does.
Steady Aim / 15% Ms Boost / Sharpshooter is what I'm currently having the absolute fastest runs with.
