I just finished posting a list for all the available specs and talents in the other thread. I plan to update it as the talents change.
It seems the biggest buff from all of these changes is the healing that the specs get from hero talents
Smoke Screen
Exhilaration grants you 3 sec of Survival of the Fittest.
Survival of the Fittest activates Exhilaration at 50% effectiveness.
Hunters have had a hard time in Mythics and PvP when no healer is present. This seems like a strong solution and its a shame its only available on dark ranger.
Sentinel does have some passive mitigation which may help in the form of
Don’t Look back
Each time Sentinel deals damage to an enemy you gain an absorb shield equal to 1% of your maximum health, up to 10%.
Though I believe Smoke Screen is far more flexible for burst and still helps passively a bit as well, effectively giving you two shields and two heals
Pack leader has access to the following
Den Recovery
Aspect of the Turtle, Survival of the Fittest, and Mend Pet heal the target for 20% of maximum health over 4 sec. Duration increased by 1 sec when healing a target under 50% maximum health.
is pretty decent as well, but smoke screen still looks strongest.
