Healing in the game is incredibly boring, though it's a product of the games overall design that makes it suffer. You're basically just a DPS with heals. Most fights are all completely scripted with when abilities are done, which means healers can basically do nothing but damage, then use their oGCD CDs in rotation on tanks for the tank busters, along with the tanks using their own CDs. Most damage that goes out is large AOE bursts to the entire raid, which again, the healers can use their CDs to mitigate and heal, and most heals are all AOEs in general, with many being oGCD you can weave. I guess some people might like the more calculating aspect of it, but to me it's slow, boring, and clunky. It was so mind numbing that I had to switch to DPS in Savage. The only fun I had as someone who always plays healers in games is wall to wall pulls in leveling dungeons. The worst part is how boring healer rotations are when they should be more like DNC/RDM 4 button proc rotations.
