not gonna dispute that a tos can kill all, but it's a consistency thing. plus, good duel toses are a rarity. so before I would rank it over conq/bs/demo I'd like to see a tos go >50% winrate over any of the classes in the long run. it's super harsh to duel on tos... conq resists one quicksand, which happens all the time, and you're in trouble. demo that knows to avoid PotSR and static blood, super trouble. bear shaman in any decent spec: silence or iron hide or general with healing spirit + prot, super trouble.
just the fact BS has a super strong winrate vs. conq puts it over the tos imo (carnage conq can't kill bs in my experience, but maybe sometime we can put it to the test, sanagav)
