Swapping out a Shaman for a boomkin and other thoughts

[Alemi]

Also, any great luck with 3s using 2+Healer?

I actually made it to 1700 with an spriest and 2 shammies and just got to 1675 with a resto druid. I've been looking for a boomkin/restokin to play with in 3s but haven't found one on my server yet.
