I can try and make some screen shots of my settings later but I currently sit above 2k with this CR as a resto shaman. I have two different healing profiles bound to the up and down arrow key. One I call mild arena healing and the other one I call burst arena healing. During normal cd's I roll on Normal arena healing, when the enemy team pops burst I swap to burst healing mode ( Healing bar slid all the way up, higher values for surging heal and totems). I also manually pop things like ascendance, spirit link, and hex. I let the CR do the interrupts, I set it to focus the target or dps I want locked out. I have found that this CR will not help you with idiot team mates, if they stand in the open during burst, this CR WILL NOT save them. This thing will execute heals perfectly and keep your team alive if they are aware of their positioning and cd's, if not, find yourselves new teammates and push glad!
