A unit that is never used, like say a 10g naked Pelagian spearman, is quite different from something just being rarely used or hard to recruit. A good aquatic unit has a clear niche - fighting underwater.But each nation I played so far has these weird shortcomings that simply should be ironed out. And since most of those nations are UW, that's what I can talk about. I could also tell you that Machaka spiders are utterly overpriced, but that's something probably everyone knows already.
A unit that is *never* used should simply not be in the game, or changed to be more useful.
Or compare to the spiders, giving them a simple cost reduction is a simple way to buff them. Giving them a new ability out of the blue to make them useful (but totally changing the role they have) would be weird.
What is the logic behind the recruitment system in the game then? Looking at land nations, you have different recruits in different terrains, why can't these dudes just walk to be recruited where it's convenient for you? Agartha or Jomon have different recruitment lists underwater just the same. You look at the roster you have - what you can recruit where, then that information will determine how you play the nation and where you will build your forts. Making it more samey is a BSB way of balancing.An amphibious unit that can be recruited UW should be recruitable on land (at least in coastal regions) as well, no logical reason it shouldn't.
Therodos dancer units have become completely useless in one of the last patches (and they were already poor before).
Therodos dancers seem totally fine to me, sometimes you want to hire them sometimes not, depending on your bless and other factors too. Even if you can't win games just by spamming them.
Some UW nations are weak I'll give you that, but I don't agree with your proposed cure. I prefer low-key improvements like changing costs and combat stats, not changing units and rosters into something very different.Taking care of all those points I could bring up about single UW nations would make all of them a lot more playable without suddenly making them super strong in comparison.
