Should Cleric Stance be disabled in party instances?

[Taika]

I'm just stating that, as long as people are not dying, a healer is fulfilling their requirement to the party.

Do you really think that a SCH "is fulfilling their requirement to the party" if they /follow the tank and go afk while letting the fairy heal, if no one dies? Because this is the argument you're making, that doing the bare minimum, if even that, is acceptable, as long as the group completes the task (in other words, if the other members are willing to put in more effort).
