Some of the super-advanced techniques, like making use of duelist, seem beyond me. Likewise with that guide that talks about using guys in a “martyr” role.
It all depends on your play style, but I find a basic mix of sword/shield, some 2H, some ranged works well for me.
In my current game, I just won the first end game crisis, a war between noble houses and my setup is:
2 Two Handed Weapons
First row is arranged like this:
Shield, Shield, Two-hander, Shield, Polearm, Shield, Two-hander, Shield, Shield
My two hands in the off-cent positions often get opportunities to use their multi-target attacks and the polearm has good options due to reach. The core of my force are the sword and board guys holding the enemy in place, and I have 3 archers looking for shots on un-shielded enemies and enemy ranged.
Also my two end shield guys carry armored war dogs and will loose them if there’s a clean shot to enemy ranged or enemy support.
Basically, my old 2-handed flankers have been moved inside where they get better targets and I use stout shield guys with dogs for the flanker role.
