This does not seem to be a quest where the QM is making every decision we make a razors edge matter of life or bad end to the quest. The arguments I keep seeing are vastly over the top for the consequences of the 'wrong' decision.
I mean, of course it isn't life or death, apologies if my tone indicated otherwise. If we forgo the torps, then the Gailleo will be fine, and its scientific capabilities will be just the same.
What would befrustrating is if we pass up on a massive upgrade to a key design capability which we can get for a song, and a refusal to look at the evidence that contradicts people's gut feelings despite painstaking attempts to obtain good information and explain it. That's hardly unusual in a quest, it happens all the time, it's just vaguely annoying.
After this ship, I want to build a mainline combat ship that has High Manuverability, the soon-to-be experimental Duratanium-Enhanced Hull Plating, and has a higher mass so it fit in more stuff too. I don't want to spend all our military budget for the next two ships on this one instead.
I mean, this is valid, but the Selachii exists, and is still a fairly new design, which we have available in significant numbers. So I don't think we're getting a significantly better high-manoeuvrability warship without more techs unlocked. Normally our build cycle for a single production run is like, 5-8 years ish? So we're forgoing a maximally combat heavy ship for one other class at most, not two, in exchange for a lot of extra up-front combat power.
Like, Sayle explicitly said it's not really an issue unless we were building the Thunderchild Mk. II for our
next class. Which would be silly, because... we aren't going to do that.
We could, based on what Sayle has said, probably build another workhorse design which was moderately armed for our next class, and it would be fine.
