This is just a personal opinion but I think what I have seen gradually become a common practice is just dying in a chaos dungeon rather than actually consuming a potion because potions cost money.
However, taking the L and dying in a chaos dungeon really has no meaningful detrimental effect, because this is supposed to be simple daily content.
I think a good quality of life change would just be that potions in Chaos dungeons are either not consumed outside of the dungeon, or alternatively just having a special potion used in chaos dungeons.
This is not sour grapes or a massive change, or even something that matters all too much. I just think it would be a nice quality of life change to fix what otherwise feels like a rather clunky game mechanic. (Dying because the repair cost is less than the potion cost)
