The windshear macro I was talking about was setting up a macro for each shaman that was like /cast [target=arena#] wind shear so I could wind shear targets 1-4 on my arena frames at once. I also put a stop casting command in front of the windshear. It does two things really, eats any groundings and spell reflects and possibly interrupts spells ... I tend to spam it a lot since making it. As far as when I nuke, anytime I get something completely purged with a weakened soul debuff and they have not pop'd a cd I typically pop it, some classes I try to avoid nuking right away just to check if their going to pop a cd .. like rogue vanish or mage iceblock for example. Also, I try to always avoid insta nuking warlocks, very rarely does that work out.

I'm glad the games are proving useful for you though, thanks for the feedback.
