Well kinda sorta related maybe.

I hate time limits. :I

Like in dungeons or boss fights. Drives me crazy. I dislike feeling like I have to rush around. So I guess I would also not be a fan of speed runs.

On one hand encouraging speed runs helps development identify imbalance. People will gravitate to the path of least resistance and then that makes it pretty easy to say "Hmm well let's look at <class> <skill>"

One the other hand it makes people feel miserable when they have to do something one way or no way because outside pressure.

Perhaps a "well-balanced" achievement and bonus chest on par with speed run for completing something with 6/8 jobs being unique to the party.
