I still think shams are the PvE team of choice ( and any tank now ) some hard packs of mobs and be easily hex/ bind elemental. Healing is harder so 4 Chs will come in handy now more than ever. 4 healing streams ( one glyphed for the extra resist ) will help a ton. But i have not boxed this expansion content yet, just going by what i know from playing my raid shaman solo. Hex and bind elemental are both awesome CCs now btw.
