I forgot to mention what Bloodtone said in his comment.
TOTH atm is essentially meant as a way for you to gain a buff yourself when using Barbed Shot that by default gives your pet the Frenzy-buff. TOTH is just a way for you to benefit more when using Barbed Shots as well.
Currently, it does not affect the critical strike chance of any attacks made by your pet.
I’m not a theorycrafter myself, but yeah, according to for example Icy Veins, picking TOTH is, in general, a dps loss over picking A Murder of Crows(AMoC).
It’s partially able to compete in certain situations, such as with heavy AoE-periods. Sometimes in M+. And apparently, any Dance of Death-trait(s) you might have, does benefit from this talent.
I guess you can take from this that, AoE through Beast Cleave(your pet) is not affected by TOTH while if you use either Barrage or Stampede, those 2 are affected by it. Might be wrong, but at least it sounds like that could be the case as the talent does not benefit your pet attacks.
Also, that most likely means that the Stomp talent would have the same disadvantage as Beast Cleave attacks, as it’s pet based.
And so on…
Anyway, looking at the BM talents overall, I would say there are several of them that are in desperate need of improvements(not just talking about numbers tuning…).
Scent of Blood, Venomous Bite, Thrill of the Hunt, Stampede, Spitting Cobra
to mention a few…
Not to mention that you have the possibility to add an extra 5 stand-alone abilities through your talents as BM(6 in total, but 2 are on the same row). All of those are just plain, press-when-ready-abilities.
When you also have talents such as Scent of Blood and Venomous Bite with passive effects that are barely noticeable. I really hope we can get some more depth to the spec in the future. Not just by thematic design but also through the feel of gameplay.
