Elemental Shamans sucked it up in the last season, shamans dps in general did from watching high end players show only games they won in 20 seconds cause of zerging with a warrior and other high burst dps in 5.0-5.1
The pc 2 pve gear appears to be just like the epic trinket from DS in the last expansion.
It has less of a chance to proc at 10% but now with the changes to each hit vs each spell cast, CL spam with protection of grounding totem is going to be interesting to watch.
I'm thinking 2 Elemental Shamans with a Rogue will be a very good 3's comp simply for the large burst of damage to come since rogues were almost buffed to the point of end of Cataclysm if the patch notes are correct; and I mean the shut down capability. Adding in the fact that the rogue and the 2 shamans could be stealth each starting game play doesn't help others.
What does everyone else think?
