Riddle me this. If downtime activities are too haaaaaaaard if they require more than a single button press, as seems to be a reasonably common causal healer opinion, and uptime activities are too haaaaaaaard if they provide more than the minimum possible chance of failure, as Yoshida also seems to believe (since they "can't tune healing any tighter), what then can we conclude? That both the downtime and uptime activities of healers must be as dead easy as they can be while squeezing under the limbo bar that qualifies them as "gameplay" instead of "movie watching"? That healers have heads full of oatmeal and can't be trusted with real teamwork activities?

Pressing one button over and over again for the majority of an encounter is literally the worst design I have ever seen in a video game, without exaggeration. "But I like it" just tells me you don't actually enjoy video games, you'd rather watch a movie.
