5.2 Guardian Changes - Part 1

I thought I'd start keeping track of the 5.2 Guardian changes. There are currently two changes I would like to highlight:

1. Mangle

When looking at the WoWHead tooltip, we can see that the rage variable of the string changes from

$?s114107&s62606[7][5]

To

$?s114107&s62606[7.5][5]

Does this mean we're going to get 7.5 rage for Mangle Crits?! I thought I'd highlight this one first because it's not noted anywhere I've seen.

2. Tooth and Claw

The most recent post on MMOChampion states that there is about a 12% reduction. The MMOChamp tool tips shows

[ 88% of AP - 176% of Agility or Stamina ] less damage

But again on WoWHead we're seeing

(max((AP * $AGI) * 2.2, $STA * 250 / 100) * 0.4) less damage

Note the 12% is from the 2.2 being reduced from the old 250/100 (2.2/2.5 = 12%)

If you notice though the common for the MAX equation is before the stam and still has the 250/100 modifier. If this is the case, we're only seeing a 12% reduction in Tooth and Claw when we don't have any vengeance  Really there is no nerf then. Personally I think this is just a typo on WoWHead
