SMN DPS rotation?

[FluffiNimiki]

Here is a general starting rotation:
Bio II+Obey(so the pet starts attacking while you're casting) -> Miasma -> Bio -> Fester during GCD(make sure to delay it a little more until the Bio debuff is present) -> Shadow Flare -> Thunder -> Ruin -> Ruin II -> Raging Strikes+Fester during GCD -> Bio -> Miasma -> Thunder -> Bio II -> Fester(have to use this one on GCD) -> Miasma II -> Rouse During GCD-> Bio -> Contagion+Spur during GCD-> Shadow Flare -> Ruin II -> Enkindle during GCD

...

I find this information very helpful, however, Thunder is no longer available as an additional action. Please update.

You are looking at a thread from 2013 afterall. There's tons of other resources you could pull from that have since been released. But Thunder can be easily replaced by Ruin + Ruin 1/2 (depending on if you use Ruin 2 to force GCD or not)
