I am aware that Arp is going away in Cata and also that it will be changing to either Haste or Crit, which ever stat is not on that piece.
My question is, what will happen to those with Arp socketed? What will those gems change to? Obviously you can put any type of gem in your gear, regardless of what other stats are on it. Before you freak out, I am not socketing Arp as a pally, I am the Plate CC for my guild and my warriors and DKs brought this question up last night and I had no answer for them.
I guess this could have been posted in the Warrior or DK forums, but I was unsure as it really applies to all of us. And since I am a pally, here I am in the pally forums.
