imo eastern archers, horse archers too should be slightly stronger. volley after volley with no effect whatsoever is a bit over the top.
i didnt mention them and only highlighted javelineers exclusively because the later's quantity versus quality issue (240 skirmishers to 160 archers) is more puzzling...
gents, remember, we are not talking about actuall killing ratio, but merely ability to inflict casualties that would cause disability to carry on fighting. this soldiers might be easily healed in the after battle scroll hence imo, improving missile attack just one slight bit will make it good and improve over all balance.
