well, having 13 is better than 10 if you need at least 11.
BoA bow provides the missing 1, but i prefer a throwing weapon. remember, nelfs need additional hit anyways, so it is not bad to stick to the belt.
if the warry is alliance the benefit is arena only^^
tbh, if you choose LC/MS you are going for stam and deviate scale belt is BiS in that case. belt + drape are 7hit...combine it with either chest or shoulder to cap.
only hunters and pallys can use [item]Lavishly Jeweled Ring[/item] to cap with the chest.
