For Agility:
Alliance > Deadmines Cleaverx2(Finish the Westfall questline and then kill the defias mobs in sentry hill, these drop often) Horde > Butchers cleaverx2
Boa > Mass of Mcgowenx2 (you could get the BOA sword MH, but IMO Mcgowen has better itemization, and I believe in symmetry)
But seeing as I'm sub and I have the extra agility built into my specialization, I'm rocking Honor Sword and the BFD sword until BOA's for the top damage. I get higher ambushes off this way.
