It's fun enough to play healer for my static, but I don't really enjoy it anymore in PF or normal content.

First of all healer is one of the least rewarding roles in the game to play with randoms. No one cares if you optimize. They don't care if you're pushing high damage, no one is dying, you're mapping the fight perfectly and managing oGCD's efficiently. They'll probably even panic or think you're bad because their health is at 50% for 15 seconds and they have no clue when the next raidwide is. The Medica II spamming healbot with less than 50% uptime and no damage however will be showered with comms and praised because people see HoT's and full health bars and feel safe. Even if they let 3 people die to avoidable damage that a good healer could have easily caught, the group thinks "wow they raised me and recovered after my mistake, best healer ever!". I've had more comms after screwups and hardcast Raises than I've ever had on my best runs.

Secondly, healer is not designed to play smoothly. Dps and even tanks are. They have the weave and movement tools they need and for the most part (there are a handful of exceptions, but overall) their toolkit has synergy, connects together and flows. WHM is clipping like crazy the moment unexpected heals are needed and blowing healing tools just to move. SCH's pet is quite frankly a mess and pays a hefty weave tax despite a wide oGCD kit. AST plays the best but card rng can still screw you over sometimes. Things like WHM plenary being an oGCD that has to be used before your weave window (Rapture), AST needing 30 sec pre-pull to use Divination properly and SCH fairy ghosting and needing re-placing frequently all function fine and aren't extremely important, but don't make it feel like you're playing a role that has time and effort put into how its gameplay feels.
