Heibai = Better polearmer
Knitler = Better awlpiker
I don't think Knitler can play without heavy armour and an awlpike, or level 35- or atleast I haven't seen it. Heibai plays in heraldic mail and a 4d weapon, much better.
As for the roster, I would try and fill all the 50 slots with myself- simply cause im the best 2h and hoplite the world has ever seen. I would have Ramses commanding the battle, because he's the second best commander in cRPG. Other than myself.
