3.0 summoner raid rotation / dps tips

[Koyuki38]

Contagion, Tri-D and DWT have the same oGCD value.

Which means for each DWT, you'll be able to cast Tri-D and Contagion to apply full DOT potency with full dot Duration.
This has no GCD cost, no mana cost, so it would never be a dps loss.

But, depending on the moment you use it, it could give you more or less dps. It's all about manually refreshing dot or not before Tri-D.

For example, if a dot expires 3 seconds before you would use DWT + Tri-D, you may not use a GDC for putting this dot that would tick only once.

Also, do not use Miasme 2 any more on single target.
Miasme 2 has 70 potency (20 + 50 dot).
We use it only with contagion, so it has a potency higher than ruin (20 + 100).
Contagion is now used under DWT, because it's the best moment to use it.
There is no point in using 120 potency dot with high mana cost when the DWT allow us to use ruin 3 for the same

potency, direct damage, distant spell, and same GCD.

Basically, the only moment we could use miasme 2 on single target is also he only moment where we have another spell that does the same thing in much better way.

We use [Miasma 2] only with contagion... [which] is now used under DWT....
There is no point in using 120 potency dot with high mana cost when the DWT allow us to use ruin 3 for the same potency, direct damage, distant spell, and same GCD.

Now here's a question. I'm not there yet so I can't test the rotation out myself, but I was thinking that going into DWT I'd use Miasma 2 to give me time for off-gcds, instead of a Ruin 2, since I'd be using Contagion to extend the dot. Like this...

Aetherflow > Raging Strikes > Dreadwyrm Trance > Miasma 2 > Tri-Disaster > Contagion

Unless I'm wrong about what is or isn't off global (I'm only level 53 right now), without that Miasma 2 in there we'd be using five OGCDs in a row, which, since Ruin 3 has a cast time, would mean it only makes sense to throw an on-gcd instant cast in there. Am I missing something in that logic?
