Talent Tier 15: Killer instinct (Increase the damage of kill command by 50% on targets that are below or equal to 35%) is the best choice in all situations since dire beast(summons a beast for 8 seconds and increases haste by 5%) got nerfed early on in the expansion.
Talent Tier 30: Chimaera shot is the best choice in this tier since it generates alot of focus instantly depending on the number of targets you have.
Talent Tier 45: This changes depending on the situation generally I use Camouflage however in raids I use Natural Mending.
Talent Tier 60: A murder of Crows is the best choice in this tier since it has a high damage output compared to the rest of the talent choices
Talent Tier 75: I use posthaste majority of the time cause it removes roots and it's on a 20-second cooldown however on fights like zek'vos I like using binding shot.
Talent Tier 90: I use stomp in this tier since it the best talent for both aoe and single target. Barrage is good but only in very specific situations like g'huun first phase.
Talent tier 100: Aspect of the beast is used since its a flat damage increase also it improves our pathfinder passives.
