Visual spell rotation for the destruction warlock rotation.
For now, this is only for destruction warlocks that use a spell rotation like: Immolate, Conflagrate, Chaos Bolt and fill up with Incinerate. It will show up what spell you need to cast at any point in rotation.
There is nothing to configure, just select an hostile target and start casting the spells indicated by addon. Using /es will bring up configuration panel with option to re size the spell HUD. Can be dragged around the screen all the time.
