the build rate problem isn`t so bad since the capital ship build rate cut. Just be glad you didn`t live in the times when sloop build rates were 10, galleon/schooner build rates were 7 each, barks were 5, and there was no MOW, brigs or R Snow. Not to mention R class couldn`t capture at all and galleon didn`t have ANY missile attack whatsoever.
Not only that, terrans could build 2 hercs, 3 nirv, and 3 tyr at a time, with similar build rates for caps on other races.
Under such conditions, you would have been considered really good if you could make a c4 and not die trying to hold it. The elite collectives managed to make 2 of them on very rare occations.
So, considering what things used to be like, it ain`t so bad. Really.
