HA vs HA - tactical help required

[zooeyglass]

hey everyone,

so i'm toddling along in my sauromatae campaign, all going smoothly, except now saka have decided to wander into my neck of the woods, with 10 units, 5 of which are their killer elite HAs. I'm using mostly Scythian riders (aorsi riders in fact) and the bog standard horse archers, and finding the saka a tough cookie to crumble. please can anyone share tips for HA vs HA battles. obviously against infantry it's a completely different approach (circle, fire on flanks and rear)...but against HAs...well.......help please!

EDIT: i should add, i find that the losses i sustain are so often man for man against the Saka that it's simply becoming a battle of numbers - more men=men left after all the arrows have been exchanged and equal numbers killed.....is there anyway that you don't just lose man for man?
