If you by update mean replace the existing ones I vote a strong no! I'm rocking t2 on both my warlock (nemesis set) and my shaman (ten storms). T2 is to me by far the best looking for so many classes, bloodfang for rogues and judgement for paladins are also both amazing. Every set suits the class so perfectly and they're not overdone or exaggerated like pretty much every set since cata.
