I haven't had a chance to do much scouting in my games yet (maybe 10 planets on average), so i'm not sure what to consider high resource spots. Is 4 metal and 3 crystal good?
Also, the behavior of shields seem to be confusing. A warp gate took shots from like 100 bombers without taking damage but when i ordered my cruisers and fighters to join in, it fell in about 2 seconds. Can someone provide a detailed explanation of what shields are and do?
