In today’s Dragonflight developer notes, Blizzard has revealed that Warlocks will have an interrupt independent of their pets in Dragonflight, with Spell Lock becoming a talent they can learn themselves.
This change is intended to allow for more pet diversity, since right now Warlocks are tied to their Felhunter if there is a need for interrupts.
With Dragonflight, we’ve removed Spell Lock from Felhunters and Spell Lock is now available for Warlocks to learn themselves.
