Three things on these guys:
Firstly the "front" no ram damage is pretty inconsistent, they'll take damage when you'd think they should not. Hard to reproduce on demand, I may have a video I can fish out. Maybe the cone just needs widened or something?
Is it intended that when claws are destroyed, they take ram damage again? Should it not act more like the imperial ramming upgrade which is unremovable?
Lastly, they have big pathing issues when attacking a ship side on, couple of times now I've had them flat out get stuck and refuse to move after a ship is hulked, which is awkward because they cannot escape the scuttle then. Can't turn, can't move it via boost, can't reverse. Just stuck there in certain death.
