Currently I have to use Divine Plea everytime it's up, ask for a Hymn of hope from our Priest, an Innervate from our Druid, pop a mana pot, and make sure I'm constantly judging. Even then, I am having mana issues. If the tank takes spike damage more than twice in one pull it is nearly impossible to catch up on healing. Holy Light just doesn't cut it.
I am all for making healing require more thought, but some of these changes just seem unfair. I mean, 7K mana for a divine light...really? Yes, I know pallies probably got the good end of the healing stick with our 20K mana free heal but don't think we aren't having the same problems that the other classes are having.
Now the world knows my opinion on the first week of Cataclysm healing.
