§1How to read this

A rotation in SimulationCraft is a priority list, not a sequence. Every time the character can act, the sim starts at the top of The main loop and does the first line whose conditions hold. Lower lines only happen when nothing above them fits.

The page shows the list as a decision tree: set what you know about the fight and your talents, and it lights the lists the sim checks, in order.
Cast lines use the ability. Hover, focus or tap an icon or a name for its tooltip.
Go through another list: its lines are checked in order; when none of them fits, the sim comes back and carries on with the next line here.
Switch to another list: the rest of this list is skipped and the choice is made from that list alone.
Helpers are values the list works out on the spot, such as “are we holding a cooldown”. Setting one takes no time and the list carries on. The tree works out the ones your situation settles.

The list is written to perform well in the sim, not to be the only right way to play. Every line keeps its original simc text under the simc toggle at its right, and the list author’s note where there is one.

§2Decision tree

Set what you know. The tree lights the lists the sim checks, top to bottom; in each list it presses the first ability whose conditions hold and that is ready. Readiness (cooldowns, resources) isn’t in the list, so a lit ability is the first one allowed, not a promise it is cast.

Blizzard’s own suggestion system (the one-button rotation), as simc carries it. It is simpler than SimulationCraft’s list and is not what Cogspark simulates.
