I absolutely love regen, as it helps me so much to solve the MP shortage preoblem. Now I have the habit of keeping regen on tank almost all the time through a fight (whether boss or mobs, unless the tank is not taking damage of course).

But I just came across a thread where a WHM says regen is useless and he never use it because it may generate unnecessary aggro from over-healing. Just using cure/medica spells is enough.

Then I recalled the ~10 times CM runs I've done, only 1 WHM (besides me) ever used regen (which I think is really good since we can then just stand there and don't even need to use cure anymore).

So my question is, for the harder end game contents I'll be doing later, should I try to avoid using regen and just use cure to control the over-heal?

Thanks for any advices.
