I played through some dungeons and trials as a healer recently and, regrettably, I realized that so long as there is a plethora of tanks who single pull and/or don't cycle cooldowns in level 90 content or teammates who consistently mess up mechanics, Yoshi will continue to perceive healers as fine because their role of cleaning up after people is being fulfilled. He genuinely believes peak healer gameplay is when teammates are constantly making mistakes.

Oh, what's that? You want to play with your friends who are very organized and know how to play their jobs? Have fun with your "211111111111..." gameplay!
