Alex, what skills are you planning to take for your commander?
1) I take "Order of Prosperity" and become a leader-commander (I can even create my own knightly order, as Alex wanted). I give allies +50 initiative, dodge, and accuracy, and I die in one round. I hope that the allies will be able to kill the enemies before they reach me. At least, most of them. And then I rely on luck and resurrection spells.
2) I create a commander (Jagensdorf) with three commander skills and slightly higher stats, or with all commander skills (Clan of the Sun) and something else (a bow for ranged combat? Massage for additional buffs? (lol) Flaming Wings for protection against melee fighters?). There will be no extra money from quests, and the usefulness in ordinary battles will not be much higher than in the first option (except perhaps through slightly greater survivability), but in large-scale battles, the character will be a monster. Leadership in organization is purely optional.
3) I just create a charismatic melee fighter (most likely with a shield). The bonuses to allies are much more modest, but he should live longer than usual. Definitely not a group leader.
