You have to respect the javelin throwers; as Rus, you can't just go only archers.
Against Byzantine javelins, you're going to need men at arms as the front line.
With five cisterns and the Golden Horn Tower, it's very possible that the Byzantines can outmass Rus even with the bonus deer income.
Rus gets faster moving warrior monks, but with the Cistern boost influencing Grand Winery, you can make a monk within 15 seconds on cistern level five upon hitting castle age.
Once the camel mercenaries are in, their debuff significantly reduces the horse archers' damage potential.
