cavalry in EB

[econ21]

I seem to be able to solve the skirmisher problem by charging in cavalry units in a double line group formation...

You mean you use two units of cavalry? To take out one skirmisher? That's a luxury it is hard to afford for those of us playing historical Roman armies! But that's for the tip - it sounds sensible. And historically cavalry does often seem to have been deployed en masse, rather than frittered away in penny packets.

The BI system of cavalry is much better, especially for ranged cavalry.
Sassanid Immortals used bows before fighting hand to hand. And this kept them in close formation, or at least that's my view of it.
