So what I'm seeing here, are two main camps of healers. One camp wants there to be more healing required so they spend more time thinking about healing and less time about DPSing. The other wants more involved DPS rotations, so that when there is healing downtime it's less dull then it is currently.

Sadly, the trend has been to make both camps unhappy with dreadfully low healing requirements and painful 2 button dps spam.
