Overhealing has got to be the most overrated "bad" term in the healing Dictionary. There's absolutely nothing inherently bad about overhealing.
The issues only arise in one of two cases:
- You overheal when you don't have the mana (old whm gameplay or current WHM when you've just been rezed and all your mana management skills are on cooldown)
- You could use that gcd to optimize your play and dps instead.
Appart from those it's actually beneficial to overheal. Now in FFXIV that second point often takes precedence in class optimisation so it isn't as obvious. But just to illustrate this point, picture an encounter where you do not dps. Finishing such a fight with 30% mana vs finishing it with 10% mana but constant overhealing.. The later is clearly better, even if it's just a matter of comfort.
To rebound on what has been said. Casting Cure II instead of Cure I does not hit either of those drawbacks. So it's a perfect example of how overhealing is good. Not to mention that you actually get the overheal back in the form of benison for later use. It's just win win.
I will however agree that this is a bit of a dick move because it goes against all the whm gameplay optimizations that had been done by players up until now.
