I’m guessing this discussion has been had internally by the game devs repeatedly as well tbh, there are pros and cons to their approach and they’re most likely very aware of it. Just like there’d be pros and cons to a different approach. My guess is that their goal first and foremost is to tell the story, and have as many enjoy that as are willing to play FF14. I do get that for veterans this might feel like they are valued less, it crossed my mind before. I don’t think that’s the case tho, more that they don’t want to exclude people.

From playing other games I’d say healers and tanks burning out and signing up less has usually been a result of making dungeons more difficult. Sometimes because they’re not that great themselves and struggle with the content, sometimes because others are not that great, sometimes because it can easily lead to shorter fuses and arguments. Neither of these things is usually perceived as fun.

If patience, consideration and the ability to laugh about things not going great are a given, it’s much easier to decide that challenge is ok and that it will promote teamwork and fun as a group. I haven’t played long enough to be a proper judge of whether this is the case here and the game devs are underestimating players, or whether they decided rightly to protect their players from those bad vibes.
