Monks have nice mastery but their dispel requires lvl24.
Good work! I would prefer https://www.wowhead.com/item=27528/gauntlets-of-desolation?bonus=6710 rather than chest for 2-set bonus and Pvp Power on cloak (6 int)
That's strange, for fury warrior ilvl 32 weapons give about 14,5 strength from their weapon dps increase over ilvl 24 heirlooms ((6-4.3)*6*1.5) so overall damage should be the same. But you get more stamina and secondaries (mastery!) from artifact weapons.
If you don't need to tag mobs (no competition) I would advise fury warrior. Kills tons of mobs really fast and no problems with self healing even in poor gear (2 crusaders ofc).
9 sp is like +4-5% dmg increase for 200 int twink, just try elemental force, queue random dungeon and check your dps meter. For vet twinks its damage scales 30 -> 51 in bg, so its even better.
