Some of the sets are amazingly good, though i see similar pattern in creating sets as in WoW. I don't like helmets/tiaras on Wiz, i'd rather want to have hoods or wizard hats. DH ones are very nice on the contrary. Would be great to have an option to turn of helmet like in WoW.
On the other hand some of WD masks look amazing (i liked those with green feathers, one with tentacles and last one).
Also barbarian set which is looking a bit Suron-like is awesome. In general all of them look good/great with exception of what i mentioned earlier.
