Hai,
(as survival)
I am using a ferocity pet and I'd like to ask a question about:
Wild Hunt vs Shark attack, Which combo is better?
1/2 Wild Hunt + 1/2 Shark Attack
or
2/2 Wild Hunt
or
2/2 Shark Attack? (This might be the worst way to spec your pet)
Also I have another question:
What's the difference between a ferocity pet and a Cunning Pet?Is the difference small or big , DPS wise?

Looking at data from our kills these seem to be rather equal in high end gear, in low end gear having 1/2 in both might be slightly better (less Sic 'Em procs).
