I'm really torn on this... I'm really worried that a tank will be required in some instances. I remember trying to do the level 80 strat with 5 shamans and getting rocked in beta - but I only make a couple attempts.

Right now I'm thinking 1x pally, 1x boomkin, 3x shaman. Mostly because I know I can do instances this way.

I'd REALLY like to do 5 shamans or 4 shaman and my boomkin, but not having a tank might be tough....

On the plus side, a prot pally is a really good healer now, so worst case I can just make the pally my healer when I don't need a tank.
