There isnt really any rotations. This expansion has made our healing style very dynamic and fun. In raids and 5 mans I use the ToR style where I BoL tank and use my HS and HR on raid and HL<FoL<DL on tank for the most part depending on how much heals they need. By doing this I generate HoPow to use my free heals WoG and LoD. The key for me to not run OOM is to spam HL's and use other healing spells when absolutely necessary. I also take full advantage of AMastery and my Hands(HoSac,HoSal,and HoProt). HoSac is always on cd and used on tank. With boss fights I use my cd's like AW, Guardian, DP, DF. This works for me. You just need to find what works for you. Goodluck man.
