PS your opening rotation is wrong.

If you delay fester until after thunder->Bio, you will most likely (barring high SSpeed and lack of lag) be running out of RS or very very close to it when you do your second fester.

For example, in your rotation you have your fester only 2 GCDs after the last fester (and also, on GCD, rather than offGCD, which is a big nono, esp during RS).

Your boss rotation also doesn't include miasma II (still sucks, Kevee!) and Shadowflare (swiftcast shadowflare, which decidedly does NOT suck).

Also there have been many, many threads on this already >.>

Though I like your rundown of our utility, you completely forget Eye for an Eye and Virus.
