It seems to me that perhaps AI Home Command Stations are too delicate. The intention can't be for these things to die really easily, or surely they wouldn't be covered by two mark V force fields, but a lousy cap of mark 1 raid starships is enough to knock one out once the other posts are down. It's a tad anticlimactic, isn't it? It's also a bit too quick, as several of the newer posts seem designed to reek vengeance upon the player, but with the home station dying so easily there's no threat they'll actually get to be a problem. Maybe a bump to a few million, nothing too drastic, would be appropriate?
