New player hitting a wall with dmg now as Deadeye TS/RoF

If anyone has some extra time, could someone tell me what can I improve for dmg wise so I could do shaper.

The main plan is to eventually get at least a 6L QoTF.

But I just don't understand what is the thing that is allowing people to hit 100k or 150k with their TS. I'm willing to drop RoF anytime if needed.
