I've looked around a bit but couldnt find out why you guys made it so, and im courius about it, since it makes the frigates useless from the beginning. (Exspecially in the beginning, ressources are raw, so i rather build a more expensive SD and one or two loronars and they survive the assults on the first plantes than build cheap nebula b2's which i must replace after each battle. And in mid-game, when i have enough ressources to pump out 10 SD's simultaneously, why would i build frigates at that point anyway.)
