You lack ranged CC answers to a Rogue/Mage burst chain - Grounding Totem the first hard CC and reset positioning behind the Druid.
Comes down to Windfury proc luck on both sides - Grounding Totem the first hard CC to avoid losing a DPS to an early stun chain.
Outlast their DoTs with HoTs and Purge the Warlock's damage-reduction effects when possible.
This favors you slightly - Windfury procs can out-burst Retribution's cooldown-based damage over a longer fight.
