The point of Leuce Epos, as I've hinted before, is that they are vital in campaign.

- Two of their units can sandwich a heavy cavalry unit with a double charge. I've destroyed Seleukid Cataphracts with Bedouin cavalry this way.

- They are extremely important for running down the enemy general. Especially if you're playing against a (cowardly) faction with very fast cavalry generals, like Epeiros, SPQR, or Lusotannan. Of course, you shouldn't try to attack a Germanic or KH general with them...

- They make excellent pursuers to mop the field clean of your routing enemies, ensuring that you don't have to fight the same army twice. Pursuing with heavy cav is possible, but it sucks, especially roleplay wise.

- Very useful distraction and general annoyance to lure away enemy troops. In campaign, it may happen that you face a superior army (like a Roman PE+Triarii+Neitos fullstack ). Superior mobility is crucial, not only with Nomad factions.
