yeah thats what i was thinking but when i test it. i get more instant exos and seem to hit harder too. but yeah burst, i haven't been able to test that yet and with the little gear i have idk if its a fair comparison.That'll take a big giant dump on your burst/dps.
You would probably be better off going protection, Might aswell try playing some form of melee hunter, mutilate rogue with swords, or a protection warrior without a shield.
