They are definitely powerful given their cost and their late-game usefulness in chasing down and routing small, fatigued units.

WO WO WWOOOOOOO STOP RIGHT THERE!!
Elmo the mounted xbow is possibly the most underpriced unit in the game, if u get say 4... split them into pairs u can harrass cav from all angles having it so that at least 2 are firing in the back, u can kill off whole units with no trouble at all i find.
I agree especially in this game their importance in chasing down routers as sometimes that is more important than using them to flank "live and active" enemy units...
