Let's talk about regen :)

... one thing I'll disagree to is that I won't use it on a DPS who just got hit because it still activates the GCD and will cost more mana than Cure I (Which in my experience is enough to heal the person to full anyway). Since it activates the GCD, Cure or Regen both will take the same amount of time.

It's definitely situational, I wouldn't (and don't) use that as the norm, but if they get hit by an AoE and take spike damage and you don't expect them to get hit again soon, I find it to be more efficient MP-wise.
