I think the problem lies in that the claw is great for stopping and turning, but not good for ships on the move. Therefore, ships can use the claw to turn their guns onto another ship, but they cannot use the claw to outmaneuver other ships because it slows their forward momentum. My proposition is two-fold: Make the claw do a bit more damage to engines, but also give the evasive ships their own tool to evade gun arcs. In fact, that tool is already in existence, it's just not good enough yet.
Phoenix Claw:
17 damage/sec to engines (up from 13)
Kerosene:
13 damage/sec to engines (up from 10)
+50% angular drag (down from 300%)
This allows evasive ships to put on a speed boost without losing all their turning capability. We already have Moonshine for the ships that just want raw speed for ramming. This will give Kerosene its own unique home as a speed boost that keeps your agility and give fast ships with naturally high steering stats a way to move quickly out of gun arcs.
