Unique Techs, worthless?

[Harkonis]

Well, so far I've seen the Massive Engine, and Massive Shield weapons. Why would you use these? 2000 cost, fire once per combat, and they weigh a heap. Even with a religious talisman so you never miss, that's only one target per combat. Just doesn't seem worth the cost/weight/risk to me.

So far the Neural net is the only useful one I've seen.

Opinions?
