I remember in one of the patches a while ago, that the developers claimed to have fixed Cover I/II promotions. This was great news to me, and I frequently upgrade my siege weapons with these promotions in the hopes of having them survive (longer) within firing distance of cities. However, recently, I heard someone say that Cover promotions don't work against city attacks, but only against attacks from normal ranged units (and, I guess, other siege weapons). Can anybody confirm or deny this? Wasting promotions going through Cover I and II if it doesn't work against city attacks is obviously very bad.
