For an experiment on mdm in SP I took a Scythian army vs a Roman in flat grass. Of the approx 1300 Romans who took the field about 100 were left alive. Romans sent a 3 unit HC push to my left flank which I drew off and countered with my Noble cav.....I set my LCA in cantabrian circles on their foot, and moved my other HC away. I let the LCA wear down his army and the AI slpit them up. Stragglers were meat for the grinder. Wear them down with LCA, lure them away from the main body, then hit them from two opposite sides with HC.
I did in my ineptitude have trouble keeping on top of the spreadout army and I lost 4 or 5 units. A human opponent may keep his troops together. And more missile troops on Roman side may help. Will try some new tests. Scythians are fun!
