Pretty much all Zora military units are overpriced as far as upkeep is concerned. Zora units are innately expensive. This was intended. Unfortunately, since unit upkeep as it stands now is half the cost of the unit per turn, the Zora are stuck with either embarrassingly small armies or a massive debt. The AI seems to draw money out of thin-air, so it is not a problem for them. Human players know nothing of this sorcery. My suggestion is to make upkeep a fifth of the unit cost. I think that is a fair price and it is also the ratio I found on the diplomat while I was comparing my Zora unit costs.
