I don't know if it is or not, but as a casual healer I can say that in most normal content, healers are braindead easy to play and mostly amount to spamming a single DPS button. If I press any heals on Scholar it is normally Whispering Dawn, Fey Blessing or Aetherpact and if absolutely needed, Excogitation and then Lustrate. But when you're used to it that's just like pressing Second Wind or Bloodbath on a DPS when you're low.

That isn't entirely a bad thing. It's nice to have a job I can queue on when I'm tired and don't want to have a complex rotation. It's my role of choice if I'm tired. I also do actually find it fun, but like on every role, it's only fun if there are large pulls, otherwise it's not even remotely challenging anyone there to use their CDs.

I think that healers have more challenge in high-end content, where I have often seen healers coordinating with eachother and planning out their healing CDs around the fight as part of the learning process. Not to mention how those heals have to be fit in quickly in some cases between explosions or casts. I have not done much high-end content as a healer. One of the fights I did it was completely braindead except one mechanic (which is why I did it) and the others were rough.
