Id have to agree with all you said here. I have gone from 28k health to 35k health on my tank with a mix of epic gems and TOC upgrade gear. Ive only farmed 25 emblems so far but its good to know there are still some upgrades to go for. My shamans are also getting pimped with almost full epic gear on all of them.

I havent finalised my dps macro yet, Ive just been lightning bolt spamming but I am still breaking 3k dps with that so im happy for now. Also love dropping all totems at once, that is the best change imo.
