Hunters are picked for groups due to their ability to not just pump damage but also provide a ranged interrupt. Counter Shot is an interrupt that should be mandatory for every talent build.
Wilderness Medicine is a good talent if you're soloing content you'll have plenty of ways to heal your pet during PVE encounters. Increasing its crit by 25% is a no-brainer. It also took us one row to buff our Kill Shot talent. Speaking of mobility, Posthaste is a great utility talent to help players move out of damage.
Trailblazer sounds good on paper, but the Hunters in general have good enough mobility.
