Although you've rewritten the text, you are asking the same question that was ignored before. We don't allow bumping here, that's what the warning is for. About your question: either you trust the OP, or come here with some maths that proves that using a GCD on fireblast is better than scorching.
Original Post:
In the OP, the movement rotation is this:
Movement Rotation: This is a rotation you can cast 100% while moving: Scorch, Pyroblast!, Living Bomb, Flamestrike, Blastwave.
Why is flamestrike mentioned, but fire blast isn't? especially with impact?
