With a paly and 4 shamans you do not need CC. When you spec your tank right ( not a healing/prot spec.) and he has the gear, you can take on many mobs at once and just burn them all down. There is no "better" team make up than this, as far as "ease" and full flexibility go. ANY team with a tank+3dps+healer works. Shaman do have some lite CC though later on, Rooting totems and hex, I NEVER use them in PvE though.
