One right point one not complete right point monarch ;)

You are right... its hard to estimate how many arrows your opponent has left. Therefore its nearly senseless to try get him out of ammo. But still mine/our tactic is to kill as many enemy archers as possible. But u need to change your front row of archers to save man and ammo. And later its all about skirmish... kill enemy archers and shoot his troops... like it was in vi... and with their att/deff stats pavs can be used as blockers very well. i dont think shooting has become much easier or trivial with mtw2.
