I am trying to find out how these things work. As far as i have been able to figure out only one of the transport ships gets destroyed/dismantled after the invasion, and the guys in that ship populize the planet.
My question is why only one and only one ship is used up, not all, or none at all? Becoz this led me to build up tiny ships that has triple thrusters and one troop pod underneath, so that i can evade the loss of a transport ship as much as i can. But i would really like that ship not to disappear since both for management and as a concept i very much rather gigantic troop carriers that can carry about 12 billion troops. They are both scary and kinda more effective. But losing one of those ships that cost a lot really hurts.
IMO these troop droppers should be reusable, and no ship should disappear at the end of the invasion.
