And you thought it was over! Well, actually, probably no one thought it was over. I thought id check the ptr wowhead site to see if stampede is still morphing, and my suspicion was confirmed.
They reduced the damage, and changed the uptime to 100%, without reducing the effect.
So now the only question is stacking with the druid ability. On this note I decided to do a little extra searching. Under every spell in wowhead is a collection of technical data about the spell. Under this spell, it has the debuff ID number for the bleed: Aura #255, with a value of 25.
Guess what other debuff has the same ID? Yes, thats right, Mangle. And it has a value of 30. So our chances of stacking with mangle are slim at best. So the only time this will likely be worth it is if you have a ton of warriors and rogues but no feral druid. Whether or not it would be valuable or not even in this situation warrants more research.
I will say this though, at least they got the cooldown fixed, and done right.
