Yeah: I'm planning to have some cavalry units, but mostly not terribly powerful ones. Medievalist heavy cavalry are a likely feature and would probably be one of the toughest of them. All the unit sizes are fairly small too, I should add; generally it's going to be a game of high powered weaponry and few troops, just because that tends to be more unpredictably fun for a humorously intended mod.
I'm sticking with Bio NatScis being a light cav unit though I think.
