I would like to add something - I am not an experienced healer...at all. I got called in to help a friend on Haukke Manor yesterday on my lvl 30 WHM. I used Eye for an Eye on the tank on each boss and for the first two, I barely had to throw a Cure out (well, except for the DRG getting hit by avoidable attacks, as usual). Do not knock how useful that buff can be!
