Armor is worthless for tanks?
I use the Pawn addon to give my gear a stat point value based for each spec. This uses the same stat weighting that sites like Wowhead use when you compare two pieces of gear. I use it mainly for leveling alts so I can just roll quick on upgrades when dungeon running or questing, etc.
However, since Cata came out, the stats have valued armor for tanks at 0. It used to be 1/10th of the stamina value.
Stamina was worth 10 stat points per point
Armor would be worth 1 stat point per point
Can someone explain to me why armor would be worthless for a tank? I understand that point for point it's not as valuable as stamina, but IMHO it shouldn't be 0.
