Honestly I'd give up one of the weapon slots and move it to the bottom for siege things to come to the top...
Not sure which one I'd think would be good to "give up" though...1h, shield, 2h, polearms, ranged?
My order would be (from top to bottom):
Siege equipment
Ranged weapons
2h
1h
shields
polearms
I think that would be the best for sieges, but would fuck over battles, so maybe switch 1h and polearms (most 1h/shielders can be "effective" hoplites if they needed to be)
