I really like these four subclasses and the flavours they bring to the Marshal Captain, I suppose if its really needed one of the Cha-based subclasses could be granted a few magic effects (Healing and buffs/debuffs) too
I think there should be four starting Subclasses:
MARSHAL Int focused - tactical warlord, geared more for lead from the rear but with choices of manuevers so one can build a true Lazylord or a more martial tactician. Focuses mostly on attack granting and improving attacks.
BANNERET Cha focused - inspiring warlord, geared more for leading from the front but could be from the rear. Focuses more on healing/temp hp and defense improvement and overcoming conditions, inspires you to fight on.
WARDEN Wis focused - observant warlord, geared more for "controlling" the enemy by predicting their actions. Would be doing a bit of the attack improvement from tactical and defense improvement from inspiring, but through debuffs on the opponent.
VANGUARD Martial focused - bravura or other style in your face lead from the front type, fighter-light. Heavier armor, extra attack, leads by example. Probably leans charisma, but I think it deserves to be separate.
