How about, in order to make the uav head much more useful during combat, he can throw it out in front of him like a sentry, this is where it gets interesting.
The head acts like a surveyor, periodically tagging the monster in dome whenever it has line of sight and increases turret range TREMENDOUSLY for as long as the head and turrets have line of sight.
Buckets specialty is area denial, because if 5 of these get placed far apart and they lock in on a monster, that things health will bleed out fast.
(I was mopping up a random team and wanted to test just how fast armour drains with Behemoth, and it drops QUICK when all five are on you)
Edit: Just to be clear, this isn’t player controlled, think of it like placing a turret but moves on it’s own scanning for the monster, and another bucket head pops out of Bucket so you can continue the fight.
