It isnt outliers and it's across all levels of play that people find healers unfun. That's why the thread and the amount of positive reactions it had is remarkable. For a long time I thought it really was just the raiders that are bored of playing healers but actually it turns out it's unfun for many casuals aswell. That's why they're giving feedback and why many are stopping to play healer. You say "why do you insist on it" when stopping to play healer because it's perceived as unfun is describing exactly what the plan is. Which leads me to the conclusion that you just dont like seeing critical feedback about the game being posted.
