Raid: Yogg-Saron

Our guild almost cleared Ulduar this week, almost.

We had to stop at Yogg-Saron. Couldn't beat him... why?
NO IDEA!

we didn't even get past phase 1. And nobody got in the clouds. well after a few attempts atleast.
I was healing and found that the movement was a real handicap here so...
Anything a resto shaman can think off to make it better?
Ihealed as much as others (except the druid) but I felt I had to work 5times as hard for it.
Had to heal guys that were close together and cry when someone was dieing but out of my range.

any idea's are welcome.

Grtz
