Somehow didn't see this post before.
So, you're asking if the band is efficient? Like if it has enough movement, ranged attacks, cc attacks, leadership, standing potential - and units to gather the gold?
I'd say since GW & shield are good in the game, you at least can deal some damage and parry some. The key guys are protected, and the captain has a good chance of keeping the band together in the face of fatalities.
Two crossbows is also seriously threatening, although it means you will likely make a dash for the best positions and shoot from there. So area denial, in a way.
You have bodies to take objectives and losses.
Against swarm bands, high Strength, and magic, I don't know how well your band will perform. It's a classic balanced human cc band. Other bands have the options to build up more pressure in every other aspect. So it's mostly how you use these men in a given scenario that decides if they're efficient or not.
By now, I should probably ask if you've had games with this band and how did they go.
