It's sad, but I agree on the Cure III thing =(

I can imagine unrealistic situations where people bunch up and stop moving for 5 seconds so I can use the spell, but then I remember that most people are constantly spread out and moving between casts of their own spells/skills.

The radius of the spell needs to be expanded to about 10 before it would become useful (or approximately the distance from the tank to the melee DPS behind a boss)
