Reduce the amount of required Extraction Expert bases
I suggest that we reduce the amount of ExE kits needed to populate a galaxy. To combat this I suggest for example if there is a 4 base slot planet then you should only be able to lay 1 base on that planet but this base gains 4x the extraction rate similar to what 4 individual kits would provide. This reduces the overall load on a client by reducing polygons and what not as well as reducing the horrible building needed to populate large galaxies as well as making it easier to set trade bots to support an entire galaxy.
As for Colonial Admin that should be removed and terraform bps should be beefed and prices increased. It's a useless as hell skill since all CA kits tend to be T3 kits wasting slots.
