I feel that archery could use some 0 slot quivers, with not much arrows in it, and not good bonus damage that would go for longbow characters who want to use some real 2h/1h+shield/polearm.
Also, add some long knife (about 60 length, mediocre damage, can block) that take 0 slots for nordic archers who want to use longbows and for example shield. Right now archers have just the hammer, and more variety is always welcome.
(maybe making some weak throwing weapons as 0 slot items would help throwing as well).
