I have a team of 3 boomkins and absolutely love them. I'm looking forward to 3v3 arena, and I'm hoping to find a resto shammy and ret pally to join me for 5v5. Although I love seeing the 9 treants (jealous of his 15) and the fact that between starfall, treants, and hurricane you can practically AoE an entire zone (if you start taking damage just pop tranquility), fear still kills me. I love having the three druids and the stealth could come in very handy, but if I was starting fresh then I would consider a 2 boomkin, 1 shammy team for the fear protection. I don't think you'll do as well in 3v3 because the druid stealth factor will hopefully mean one dead teammate on the other factor almost immediately (pop out of stealth with a starfire, typhoon, cyclone other two if in LOS). One nice part about druids/shammys is that they can heal... I'm hoping that when I'm looking for 5 man when I hit 80 the fact that I can heal will be enough to find a tank and then I'll be ready to go.
