"Shield

Shield unique variants are as with Armor, except they can only grant bonus protection against damage types (normal, piercing, elemental or shadow), and not status resistances. "

I have seen in Auction House a shield with Freeze and Shock resistance. Could it be Punch UV roll goes against what's stated in the WIKI?
A quick answer would be appreciated, on wether it has already been fixed or is yet to be noticed! (Because I'd like to roll for 3 UVs on my shield =_=)
