i did some testing on SA vs skirmishers. SA can on average fire 8 rounds till the skirmishers close up (walking). But, the most they could kill was 1, read one, man!!!

480 arrows fired -1 man killed

and that is just the first half of the story. the skirmishers killed on average 10 archers with their first volley!
the best was 19 kills with their very first volley!!!


and some wonders why no one wants to play against the mongols!!
