A modest proposal
Making planetary invasion more flexible

Orbital bombardments.
Basically, a fleet could cause damage to a planet's structures/population by attacking it, up to 100% of the improvements/population being destroyed/wiped out.
Mitigate this by building the 'Bomb Shelters' improvement, which cuts population loss to a maximum of 66%, and the 'Planetary Shields' improvement, which limits structure damage to 25% of all structures. I guess also have a 2nd tier upgrade for both of these which doubles their effectiveness to 33% and 50% respectively.
Thanks for reading and for any input
