Tell me what you think of my list and what i should add or take away. Thanks
Aragorn
12 rangers of arnor plus 3 with spears
Captain of arnor with shield
12 warriors of arnor
2 rangers of the north

I think running away will be the big fall of the army but i think its pre solid every where else. 500 pts to the mark

You need one more Ranger of the North or Dunedain to take advantage of their superior bow limit.

Personally preference would be to run your second warband with Halbarad and more rangers, but the would require another 3 RotN/Dunedain. Other than that, a good skirmish army.

I dont think so... I think i have the right amount correct me if i am wrong tho.

You need one more. 2 affords you 8 rangers with bow which also fills your regular 33% bow limit. You need one more ranger of the north to allow you to use a full warband of 12 rangers with bow. Unless you're using the culture bonus from throne of skulls in which case you can't field the warriors of Arnor

I see thank you
