I don't think the Hopper is too strong, I think the others are too weak. Buff skyjacker because it only explodes under extremely specific conditions and even it takes so many shots you'll almost never get a kill. If it absolutely nuked flying enemies it would be a good counter.

>drill and goldrush
Leave as they are for now
>overhaul
Some kind of unique personal defence weapon, like a grenade launcher to give it a better chance at close range, without making it too strong.
>rook
Improve horizontal thrusters while keeping vertical poor. Make it more unique in its ability to boost along the ground and strafe without being able to fly around well.
>dredge
Unique energy shield to act as a regenerating HP pool so it can actually tank. Give spawns much closer to the objectives.
>overhaul
Improve mobility somewhat. Give it a large and small weapon on both arms and remove the weak left arm meme. Make it a glass cannon. Give same spawns as dredge.
