I liked healing in MMOs when all I had to do was click healthbars to fill them up. Other people did all the hard work of actually fighting monsters, and I got loot!
Now MMOs want to make healers "interesting" so that more people will play them, and this means I have to contend with actual mechanics and sometimes even deal damage. Sorry, my brain does not multitask, I'm simply not cut out for this anymore. :P
