I've read the advice from good players about not trying to build every improvement, and I've read that barracks are important, but not one in every town/city. How many rax are enough for various map types and playing styles??? I'm a peaceful builder, but I try to keep a good defense using offensive units (learned THAT here too ), but until you get rails, it takes time to get back to a rax to upgrade units...and on an archipeligo it's almost impossible. I end up building one in every town, but I know it's probably a waste of shields. Are there some good rules of thumb to go by? Do you constantly move units back and forth to keep them up-to-date? Thank you for any advice.
