Another good thing to keep in mind is that it's generally worth saving Spur for (Rouse + Spur + Enkindle) but Rouse can pretty much be used anytime it's off cooldown and you can squeeze it between GCD. If you know the fight well and the ~time it takes to get through certain phases etc. then feel free to use Spur whenever you think it's appropriate.

If you're on a PS3 you may want to macro Miasma II and Contagion together. Bio II-->Miasma-->Bio-->run up and use Macro Miasma II + Contagion. Switching between your normal hotbars and pet hotbars on a PS3 is really...awkward and can probably eff up your timing. This makes it a bit simpler, keeps Contagion from being macro'd to a commonly used ability and still allows you access to it if you don't use Miasma II (normal hotbar access).
