Think you should add a medic bot that can heal the other bots.

i already have the sprite for one. an "engineer bot" ,which when placed in squads acts as a combat medic. when places alone by the player, they will run around repairing buildings nearby

Cool, one issue I have is that when I group different bots together, my flame bot kills everyone else.

haha yes.. i wonder if i can make a research which makes your bots immune to fire as an 'upgraded' resistance.. something for me to look into!
