You lose most burst races here - bubble through the Rogue's Kidney Shot and let DoTs do the real work over the following minute.
Fear the Mage on cooldown to stop the kite/burst loop, and hold Blessing of Protection for the Rogue's second CC chain.
Similar plan - Death Coil out of Kidney Shot if timed right, otherwise bubble and reset.
A slow grind - whoever dispels/outlasts Fear chains better usually lands the DoT advantage that decides it.
