Those multiple weapons come at a ridiculously high research cost. Acid weapons (like torpedoes) have too small of a damage ratio to really be useful. You can max out DUCs before getting 2 levels in Organic Weapons (except maybe on high tech cost). As I showed earlier, it take a lot of levels of Organic Weapons to get them to be as strong as DUCs. But by the time you have spent that much research, you could have maxed out PPBs (as well as researching plenty of other stuff). PPBs are stronger than all organic weapons. They only suffer from the slightly lower range at the highest levels of Organic Weapons (which cost a ludicrous amount of research).
The different kinds of weapons quickly doesn't matter too much, really, because most of them are useless compared to the other Organic weapons. Researching many levels in Missiles is generally a bad idea, as PDCs easily overwhelm missiles. So, the fact that you get beams and parasites from 1 tech area doesn't really give too much benefit.
Spoon, I assume that you are implying the use of retro-series builds there, and discounting BSYs. DUC and PPB ships can be retro-series built just as easily as Organic ships can. Sure you can build them faster, but pound-for-pound, they do not match up to normal ships in combat.
Its nice arguing against multiple people at once.
