Question Regarding Proper SMN Rotation Concerning Giant Bavarois

I recently got in a very heated debate over what was considered the proper SMN rotation on Giant Bavarois adds
Party set up is as follows
SMNx2
WAR
WHM
The differences in rotation where as follows

I would save up Aetherflow so I could spam down Energy Drain, Ruin II, Miasma II, Bio to get down the puddings as fast as possible while running around sprinting if targeted by the boss. The Summoner who disagreed with me made the following statements
"That a SMN can't kite without Titan" (I attempted to argue that it was possible to kite with movement speed from sprint and Bind + bursting down fast enough on adds.)

The other Summoner's rotation looked something like Bio II, Miasma, Thunder, ect (non instant cast spells on adds. Ruin I instead of Ruin II) I'm coming to the forums to get clarification on what exactly is the best way to burst down the adds.

Maybe I'm doing something horribly wrong and I don't realize it.

your best dps come from the dot, they are 50% of your dps, your direct damage only represent 25% and same for the pet, then...

personally if i was in your situation i will dot the boss and when the are all gathered by the tank, spread the dot. and only there i will use the ruin/ruin 2
