If you just remove glare it fixes the problem entirely.
All this problem are just from the assumption that healers have to be pressing something 100% of the time. There are plenty of games where supports don't have to deal any damage and just have downtime between healing. Only in XIV do people complain "dps dps I want to dps" as a healer. As you all say not every role has to be the same, dps and tanks are already told to press buttons 100% of the time and optimize their damage, so why can't healers have less stressful gameplay to satisfy players who would rather not have to optimize every second of the fight to press one more glare?
