Basic Principles for WHM - What and what not to do.

[Spoekes]

Not really. In a lot of situation you don't even have to heal the DPS. But when you do it's more MP efficient to just throw out a Regen if they shouldn't be taking any more damage anytime soon. It's a misconception to think that Regen is a cure-all for DPS, but it's an incredibly useful spell and sees far more use than Cure III by most WHM from what I've seen/heard.

We have a misunderstanding here:
On this very forum I read more than once "Regen is enough" in the case of topping people off. I should have worded it differently. What I mean is, that Regen does much more than the needed top off, hence the 500 HP example.
Obviously, you use Regen more often than Cure III, thats not the question.

Wait what? All this time I should have been cure IIIing them?

Seriously though, regen is perfectly fine, it's the second lowest MP cost option we have and any further damage taken in the following 20 seconds will boost it's efficiency far beyond anything else this side of an opportunistic freecure.

At the risk of getting personal, you're off your trolley mate. Every single last ability we have could be classified as inefficient if you use it wrongly. Regen used appropriately is the most efficient bread and butter spell we have.

It is you that is saying Cure III is "MP hungry", your basically saying its inefficient, and I'm running in circles showing you that it is saving MP and GCD against multiple Cure IIs for example, and less potential to overheal if there are only 2-3 stacked targets that need healing against medica - Yes, it's very situational
Maybe it's the fact that you can do without ever using Cure III in every situation just fine what makes this spell so undervalued.

And really lame joke to throw that comment about Regen completely out of context. GG you win.
