I'll be the first to comment.
Personally, I think Ulduar gear artwork is pretty crappy, and imo worst of all its expansions and big patches. I understand Blizz is trying to create a stone-giant-mechano feel to the pieces, but it sorta gave it the long-round-hard-lolliipop look to it.
I really hope they put more animation into the pieces, like moving gears, electricity, flashing bulbs, fire-breathing, rather than the standard-fare iron-looking pieces.
I can't find any new nice looking gear other than some T8 pieces and the PVP mount. The rest are just butt fugly.
Hopefully, they improve it before releasing 3.1.
