Interesting thought. I find it to be the case that whenever you dislike a job, you kinda welcome it become part of a job you like just to make sure the job doesn't survive by itself.

What I mean by that is, I disliked Corsair and I am happy that the job won't ever be added in FFXIV cause it got implemented in AST via the card system. Same for DNC. I hate DNC but I wouldn't mind if SAM gets a sword-dance mechanic and absorb the DNC job in the process.

In other words, since DNC is going to be a thing one day, I'd rather it be part of another job than be added as a separate DNC job.
