Sneak hit works wonder if you always stay close to the boss, hence a sweet match for Hackapell. Hackapell is melee --> your moving radius around boss is the smallest in archer tree --> the easiest to adjust positioning. Tried Rogue 1 in my Musk build, eventually i grew tired of the positioning so i switched to Appraiser instead.
Gonna be even worse if you immobilize yourself with Kneeling shot frequently.
