Raptor is NOT an option:

1 debuff every 6 sec.. single target..
Use tallstrider instead:

Applies all 3 debuffs at once.. AOE: 10y range..
Yes, i know - it looks ugly.. but aoe armor reduction, 3 stacks at once - it is amazing!
I just made you a better hunter.

I use: sporebat(5% spellhaste), revager(4% physical vulnerability), raptor(12% weakened armor), hyena(10% attack speed), wind serpent(5% magic vulnerability).
Rarely i have to change them for wolf(5% crit) or cat(3k mastery).
And since i love the ability to switch from bm to surv as i please, i don't carry any exotic beast with me.
