I recently got my hunter to lvl100 and i have been checking out various PvE guides for all 3 specs.
Most guides suggest taking Lone Wolf/Adaptation in almost all PvE situations, except some specific AoE moments where Focusing Shot could maybe be a better situational option.
This situation saddens me greatly since i really liked the idea that the other two talents bring.
I must say that "Focusing Shot" should (IMO) not have the "can't be cast while moving" restriction.
But it's basic idea of "getting more Focus faster" feels really nice (instead of spamming steady/cobra).
Either way i keep hoping that 6.2 will have some much needed buffs for various underused talents.
It sucks quite a lot when one talent (on a tier) is far superior to the other 2 choices (for a certain spec).
Greatly kills the fun and variety when picking something that is not optimal (like Stampede) will just cripple you
And most of the talents are okay design-wise, they just need a number tweak... which really should not take blizzard much effort.
