I think boomkins are like hunters-- some amazing capability if you play them well. The nice part about shamans is that they continue to have great resistance to fear, and they have a lot of "passive" advantages.

I agree that they will be even more awesome when you can utilize dual-spec and instantly convert them to Tank+Healer+3xBoomkin DPS for instances. That's really compelling.

Keep having fun! I know I am really enjoying my hunter squad, even if they aren't as uber as multi-shamans can be...
