The hit point system is new in Col2 so should we have new buildings to complement it. Maybe an unmanned two stage building (like the warehouse) with a medical clinic healing everyone in two full turns and a hospital healing them in one full turn. Or would that give the player too big an advantage?

I don't know about playability, but it would be historically inaccurate. Maybe throw in a 33% chance that the unit dies completely? :crazyeye:

Well, historically inaccurate unless you have a new building called Leech Farm and new a new colonist type of Expert Bad Humors Remover. Heheheheh =)

There is still the Medic Promotion on units.
