I am currently having an argument with a guildie trying to figure out the best spec for our Wolves. She is Marks and I am survival and we're debating the best talent setup

Mine is:
2/2 Cobra Reflexes
1/1 Dash
2/2 Bloodthirsty
3/3 Spiked Collar
3/3 Spider's Bite
3/3 Avoidance
1/1 Call of the Wild
1/1 Rabid

Hers is:
2/2 Cobra Reflexes
1/1 Dash
2/2 Bloodthirsty
2/3 Spiked Collar
3/3 Spiders
3/3 Avoidance
1/1 Call of the Wild
1/1 Rabid
1/2 Wild Hunt

So my question is under the talent Wild Hunt does the 10% more AP contribute to the total amount of AP Hunters buff their pets with or does it multiply? eg. If the hunter contributed 30% AP to the pet would it be 10% more = 40% or contributing 10% more x the 30% = 33%? If the first example is the case than is that talent more beneficial than the 3% more damage given by Spiked Collar? aka is 10% more AP more damage than 3% more damage, im not sure on the pet ratios how much AP =s 1DPS

Once you have the gear, my guess is that using Wild Hunt will scale for best DPS.

On a related note:

Where can I find a tamable level 80 wolf pet?

Any advice?

I run with:
2/2 Cobra Reflexes
1/3 Great Stamina
1/2 Bloodthirsty
3/3 Spiked Collar
3/3 Avoidance
3/3 Spider's Bite
1/1 Call of the Wild
1/1 Rabid
1/2 Wild Hunt

You can also do 1/1 Dash instead of 1/3 Great Stamina. I just prefer the stamina for greater survivability on raid bosses. Plus bosses usually don't move that fast.

Neither one is the best for pure DPS, the 2nd point in Bloodthirsty can be replaced by a DPS talent. In your case Wild Hunt, and in her case Spiked Collar. You could also forgo Dash and Bloodthirsty altogether and go for one point greater stamina, one point Charge.

Pet discussions exist already. Look in the appropriate thread and post there.
