Eagle Runner Knights r like Longbowmen w/ bonus toward cav, like a ranged cav unit, only w/ 1.5 ROF.
With the 4+ range and all the Knight upgrade cards, they r SICK.
They have soemthing like 237 Health, with 26 ranged attack, w/ 2.5x cav, which like Walker said, can hit and run.
They do better against inf, than Jag Knights IMO, and you cant attack them with any cav force, or else they get slaughtered.
Using Eagle Runners w/ arrow knights for siege and anti arty, is a devastatin combo, along with WP on firepit.
