I think if you Fester before the Thunder, you can get a second Fester in before Raging Strikes ends. I also stick a Miasma II in after the Shadowflare before I start my Ruin spam. If Swiftcast is available, I'll Swiftcast - Raging Strikes - Shadowflare - Bio II at the opening just to get the amazingness that is Shadowflare up and running sooner rather than later.
