Reference (Icy Veins)

Reference only, off by default: the Icy Veins and SimulationCraft (Soul Harvester) order reads DoT timers, Nightfall and Shard Instability, which Midnight hides in combat. Haunt before the pull; Seed of Corruption on three or more engaged enemies without your Corruption; Haunt; Agony and Corruption or Wither under 3 seconds; Dark Harvest at two shards or fewer; Unstable Affliction at 5 shards; Malefic Grasp, else Shadow Bolt, on two Nightfall; Unstable Affliction on Shard Instability or at 4 shards; Drain Soul; Shadow Bolt. Reminders: Summon Darkglare once Dark Harvest is cooling, Malevolence, your Felhunter, and the shared ones.

Adapted from Icy Veins: Affliction Warlock rotation (Midnight), SimulationCraft: Affliction Warlock default list (SH_st).

In game: /rm set affliction-icyveins chooses it by hand; it loads only for its edition and class, and is listed only for the specializations it is for. It ships disabled: an alternative to the recommended rotation for its specialization. Turn it on in game (Rotations, then Enabled) and either turn the other off or give this one a higher priority.
