Ya, ive had my subjucated lands longer, ergo they have higher regional mics and ive been upgrading them to lvl 5 for carthage refroms, i do however need a type 4 but wish to return it to type 2 after all construction is done. I guess its an exploit, but seeing as ive started construction and invested so much money thus far, ill finish it and next time wont do this to try to get a better gameplay exp.
