They're a MONSTER now, with MORE ammo than a Fian Champion and a *noble bow*.

Also early battle testing shows that horse archers and other units using ENGAGE(F1-F4), kite extremely effectively, making the Khans Guard, at least the temporary BEST UNIT by far in Bannerlord:

Bannerlord's 1.5 UPDATE Crowns a NEW EMPEROR! - Perhaps the Strongest Unit... Ever?

It's early and things might change(it's beta after all), but they are unbelievably powerful now...
