I believe the robot and Mr. Wilson are in need of rework the most at the moment.
The robot has no command effect, but it requires devouring a large amount of resources. I believe that its advantages should be expressed more clearly. And instead of devouring gears, he should have some kind of crafting items.
Or, in general, you need to give him an analogue of Living Artifact, only without invulnerability.
In general, the robot should be fat, powerfully damage and drink huge cans of healing. (Very similar to mmo rf-online Accretia tank. And its funny.)
I think the Wilson needs to be made a support. Give him the opportunity to craft good first-aid kits and brew potions to strengthen allies, such as running steroids and attack speed. For a scientist, this is just right.
