With the newest PvP Essence, Boomies and Ferals will be forced to always take this essence since both are raid buffs that no other spec brings, and we’ll be forced to use it practically on all content, Mythic+, Raids and RBGs. 12% raid Spell crit and 5% melee crit on the raid completely trumps all other essences. On Boomy this just shows how few actual dps pvp talents we have available that you could place on this essence, since you removed Celestial Downpour, Crescent Burn is not a good PvE talent playwise and the rest are all survivability talents.
A more interesting choice would be an Essence that allows you to pick an additional talent from your PvE tree.
