I am sure people are sick of me saying it but I will say it again here. I would rather they roll more support aspects into the healer role than just give them DPS rotations. I feel like giving healers a DPS rotation or a burst phase of any kind will make them feel more like DPS with some healing abilities than healers. Even though the amount of healing abilities will greatly outnumber any DPS options they have, the fact that you spend far more time utilizing your DPS rotation or whatever else they provide will make them feel more like another DPS job than any kind of real healer. Support abilities are very hard to balance though, and depending on who ends up doing what can make one job essential and another useless.
