I'm looking for ways to improve my healing in SoO raiding. I'm never running out of mana, so I think I need to change my gems or something. I've been using Mr. Robot to tell me how to reforge and which gems to use. I have a log that people can look at, I'm Silandra  http://www.warcraftlogs.com/reports/f4NrhHK9xJPaVz2b#type=summary&boss=-3
 
Any help would be very much appreciated.
