I know this is an early release of this Essence but the PVP talents offered on this Essence varies from vastly useful to just plain boring. Druids for example got 2 very strong PVP talents that will effect the whole raid or party with Moonkin Aura and Leader of the Pack on the other hand Warlocks got 3 really underwhelming talents for their respective specs as well as most other classes.
If this Essence is coming in at least make the Demonology warlock essence give us the pvp interrupt talent instead. Seriously this Essence needs some re-thinking in the talents it provides.
