Their burst is faster than your DoTs - Fear early to buy HoT stacks, and keep the Druid rooting the Rogue to prevent a clean reset.
Dispel-heavy Priest can clear your DoTs - reapply immediately after any dispel and save Death Coil/Fear for when the Rogue is off cooldown.
Whoever lands Fear on the other Warlock first gets a DoT lead that's hard to claw back in this drawn-out matchup.
Kite the Warrior with roots/Fear and let Corruption/Curse of Agony chip him down; avoid trading cooldowns in melee range.
