I was thinking that +15% crit for all 5 would make chain lightning spams that much sweeter. The only problem I'm having is keeping up with heals when one of them gets mobbed. I probably just need to work on my macros for targeting heals when needed. I was thinking of trying two Shaman with 41/0/20 to keep spell hit capped at 16%, while allowing the other 3 to use 40/0/21 for the NS when a heal is a must. Another idea is to spec one of the shaman Restoration to be able to use Mana Tide Totems when mana is an issue as well as Earth Shield and better heals across the board. This would allow the 4 DPSers to continue puting out damage while the 5th shaman keeps the party healed and full of mana.
