The ambush package for sure.
I know Snipe and Aim Shot don't make use of my crit chance and if I play my cards right, I might be able to use Aim Shot the next round too, so I'm leaning towards here myself.
Now I encoutered another question - does His and Run make sense in a build like that? I plan to wield a Spearhead with Strafe. If so, is it worth to spec it? On the other hand, I suppose I'll be mostly shooting from a corner or using Ambush might mean that I might not need it that much.
Same goes for Premeditation. I'll be mostly using Contraction which is fine without it, maybe Increment here and there. Thank you for your insight!
