Lei Shi - skip get away phase

As soon as she starts channeling Get Away! simply have your hunter drop a flare on her and she'll stop casting.

You want to skip this because it does massive damage and hinders the rdps. On heroic it's extra dangerous because people with stacks are flying around, increasing damage taken of people who happen to run through them. If you skip it you get a fair 30 seconds of free dps on her, and it'll spare the mana of your healers. You can even drop it before she casts it and it'll instantly break.
