Really really enjoying the new Palace of the Dead but one clear issue for solo is the Time Limit. From floor 21+ the time limit becomes a major major problem. The random factor is fun but when you get bad luck you really need to take a little extra time being more careful since your gear and items might be severely lacking. However due to the time limit there is a extra level of frustration that does not increase the difficulty it just makes it either impossible or frustrating. Especially when 40 minutes into it you are still struggling to beat enemies due to bad luck with items and gear but you NEED to kill extra to at least make up a little for lack of silver chests.

Luck is a big factor which makes each run fun and unique but the time limit turns that bad luck into a serious frustrating hurdle.

Also, rewards. Even if you fail you should gain 'some' experience gains on the class you went in as, perhaps a percentage based on floor you were able to get to. Perhaps 9% of total per floor with the last floor being worth 19% to award more for completing it. Pretty much just anything because it is a really fun and unique way to level other jobs but not even close to being worth it based on time vs reward compared to many other ways.

Anyways, just some thoughts and suggestions based on my opinion
