I think there’s a problem with how jobs aren’t well-balanced for dungeons. Dungeons are played by the majority of the playerbase compared to raids and a lot of people judge jobs from how they play in casual content. While all jobs can clear content, some jobs are just strictly better for dungeons while others take more effort or bring too little to the party.
Some tuning to jobs based on dungeons would help Dark Knight be less of a pain to do big pulls as most of their problems with mitigation and self-sustain is most evident in dungeon content. If dungeon balance was considered more, it wouldn’t feel as bad to take into dungeons and people would stop automatically leaving or harassing you because you chose to play DRK. It would also help Scholar not have to burn through so many resources during trash packs which other healers can do with less effort. Or when paired with a bad tank who doesn’t use their mitigations. And party buffs like chain strat or bard songs barely feel like they do much in dungeons.
I think some problems people have with jobs could be solved if dungeon balance was considered more. If dungeons are supposed to be clearable by all jobs, I don’t see why some jobs should require more skill to do as well as others within it.
