hi alien poptart!
There are plenty of plans for future bots, just no time/motivation to actually make them. I have some sprites waiting for an "engineer"/repair droid but I haven't actually put it ingame yet.
Your ideas are appreciated, I think some of them are very worth doing, and i've definitely wanted to make some crazy mech robots which can solo some large nests for the end-game. Obviously the more expensive robots means (hopefully) less of them, and people can have more performance due to less pathing and less number of squads.
There might be issues with having multiple attack types on the same robot, the programming only allows 1 main attack type. for single, special units I can make "script attacks" which are basically programmable attacks, like throwing a grenade every X seconds at the nearest enemy etc. can be handled from scripts.
