HELL NO!
The latest PTR Build has introduced a major change to the Beast Mastery tree.
- The Beast Within now lasts 10 sec (Down from 18 sec) but now also increases all damage you deal by 10% at all time.
- Bestial Wrath now lasts 10 sec. (Down from 18 sec)

I don’t like this change at all. For one, this is going to seriously hamper BM’s viability in PvP. 18 seconds of immunity cut down to 10 is a deal breaker for sure. Right off the bat, I see this as a kick in the nuts for BM PvP’ers like myself. No bones about it, this change has me reeling from a PvP standpoint.
I haven’t seen any official comments on this, but it seems as if this is Blizzard’s attempt to bring Beast Mastery’s PvE DPS more inline with MM and SV. Gah… this is so misleading.
At first glance you may look at this and go, “wow, a 10% passive bonus to DPS… where do I sign up?” 😀 Let me tell you… the only time you’re going to see a huge bonus from this change is when your pet dies during a fight.
While a 10% passive bonus to Hunter DPS is nice, keep in mind that it’s a 10% passive bonus to weenie Hunter DPS. BM “Hunter” DPS sucks balls. It’s the pet that’s doing a good portion of the work.
What we’re losing is eight seconds of a 50% DPS increase for 45% of our DPS (this being our pet of course). Now granted this change will probably push BM up a teensy bit, it’s not going to be the 10% damage increase this changed tooltip would have you believe. I’d venture to guess it’s only going to be a couple of percent at best – like maybe 2-3%. Piss on that.
