While it's not a precise response to your questions, Lactose, I'd say see Osse's numbers (
Beast Mastery Bible) from the BM raiding thread. In his information, it shows a minuscule mana pool (I want to say right around 5k or just under) but stacked crit and AP with a BM spec. Between Mana Stream, JoW, and Fel Mana he refreshes his mana pool 3 times over. This is without a shadow priest, mind you.
Personally, I'm getting to the point where if I can get JoW up and Mana Stream, I pass a shadow priest to someone else who might need it more. As BM I simply can't convert mana to damage fast enough, even at full tilt (I have efficiency; if I could rely on a good support group more often I'd simply drop efficiency for Imp HM).
Anyway, back to the OP. I don't want to sound deflating, but nothing you've posted is new. You've got to provide either a solid mathematical model or empirical data to support your claims, otherwise they're not much more than opinions. I don't think anyone on these boards is poo-pooing survival; alot of the recent conversation has focused on BM spec for raiding, given the upcoming changes in 2.1 that will probably expand it's margin of damage over Survival and Marksman. Also keep in mind that there is a survival viability thread already in existence, and as such I would expect this thread to be locked soon.
