I always mark targets, I assumed that was a given

shield lob + fast blade mob 1, if I have an over-zealous healer or have a rejuv on me...the mobs will B line to the healer before my GCD is ready for that flash. I tend to prefer to not run after mobs that are chasing a healer who is running away from their tank.

I don't have step 5 yet.

Mana down to 20% or so, is like 4 flashes maybe 5 I think at my level...and it seems to have been that way since I got flash. The mana costs scaled all the way. If I didn't have flash or if it was on a longer CD, I would do what you have listed. But why over complicate it? When I'm worrying about positioning/orientation, CD usage, watching threat on all the mobs, I could do it that way, but if it works, why complicate it?

That said, when DPS doesn't follow marks, I do spam my flash just as above but then I do rotate my combo across all mobs just to add more threat. But if they are, why over think it?
