It's frustrating, because Square Enix has gotten half of healing absolutely perfect: the class "feel" and aesthetics. Playing a white mage is just bliss from an aesthetics standpoint, and the spell toolbox is pretty solid.

But then the other half - content to heal - just feels bad. The binary nature of damage and how over-provisioned healers are for incoming damage output means that that healing kit lays fallow, as I play the "heal as little as possible game" and spam glare over and over and over and over and...

This is a problem with any MMO to some extent; as your group gears up and learns mechanics you have less and less to do, potentially swapping out healers when content is on farm. But FFXIV takes it to the next level by giving everything a giant telegraph and whittling down the unavoidable damage to almost nothing.

So I end up in the following cycle every expansion:
1. OK I'm going to ignore WHM and play a nice damage dealer this time.
2. Ooo, but I remember WHM being so damn aesthetically awesome!
3. Level level level.
4. Oh yeah, there's nothing to heal.
