In case you return to this thread once more KO, I'd like to second the comment that sacred cavalry are, on the whole, a tad too pricey for what you get. It seems that perhaps there is just a multiplier being applied to cost, and while that multiplier is correctly applied to infantry, cavalry with their higher initial costs and higher initial stats do not gain any greater additional benefit from the bless than infantry do. Most blesses do not magnify a units power, but simply add to it.
So my point being, I think Tiger Riders are a bit high priced. I did a number of tests on different bless builds with Bandar Log, and by and large none of them are effective at early growth as the tried and true elephants. This just seems a little sad to me, that dual blessed tigers can't beat the ele. Sure, they are superior in some ways, but with no bless at all, there's almost no point whatsoever in purchasing them over elephants.
I think that perhaps your argument of how many of what units you would value more, breaks down a bit when you add the distinction of capital only. Capital only troops perhaps deserve to be just a little more cost effective, to encourage you to make use of them in your armies as you can afford to. Otherwise people will gravitate towards more easily replaced units to fill that particular niche.
On the other hand, I do think that recruitable Gandharvas may be a bit much. Though mid game summons like that might not be too bad with high resource cost, so that it's not worth buying them early on when you can't get a good squad together in any timeframe. Boosting gold cost may make them unattractive at all points of the game, especially if you are modding the summoned unit rather than copying it - as that will mean that summoned units gain the same high upkeep costs.
One other thing this made me think of (dear god, does he ever stop??), was that looking at what people will pay in gold for a particular summonable unit, brings into stark contrast the poor returns that you get from alchemizing. It seems people value units in the range of 30-50g per gem or more in some cases. Just makes me think that the pace of the game could be kept in check a bit if people had more incentive to alchemize gems for cash, rather than saving for more SCs.
