i dont know if this works in EB, but for AOEII, this wors well: i used to play as the Teutons, and their Teutonic Knights cold kill anything in thier paths(30 of them killed over 150 enemies!)- except for skirmishers. the skirmishers only did 4 damage per javelin, but many of them could be deadly. my knights were too slow o catch them, so i found the unit they were attacking, and i sent that unit back, and the skirmisher would follow and walk straight into my nights, where one swipe would kill them. so many bydrawing them in, the enemy skirmishers would follow, but i doubt that would work. the AI has to be smarter than that....
just an idea....
