[BUG] Furious Howl different ranks stack with each other

[watchyoursixx]

1. Current Behavior

1.1. Description

Currently Furious Howl pet ability stacks with each rank. This means a hunter with call stabled pet can cycle through 5 different leveled wolves and stack up to 5 different abilities to last about 10-20s before a pull. Not a huge boost but 757 AP at lvl 70

1.2. How to Reproduce

      1. Cast call stabled pet - lasts 2 min or until combat
      2. pull out wolf, cast howl
      3. pull out another higher lvl wolf, cast howl. Repeat 2-3 until no more slots
      4. enjoy huge AP boost to start a fight

2. Expected Behavior

2.1. Description

Furious Howl should not stack with different ranks.
This may actually be blizzlike as I don't see any discussion about it back then so it could've worked or not

2.2 Source Material
