Personally, as long as you can make use of a decently maxed stat character, in this case in spd and dex, to learn other dungeons to be comfortable to run them on un-maxed, then you’re doing great in my book.
But if you really can’t stand to run anymore sprites or snakes without doing something else in between then you’re always free to maybe try and run other dungeons such as libs, sews, etc. un-maxed for as long as you think that the person or group heading in can help you to learn and survive in the dungeon; worst case scenario, you lose a 0 almost 2/8 character with some gear saved up, trying to learn the dungeon.
And while the thought of dying is not ideal, especially when you’re living off of the things you pick up, the experience you gain may help you out a lot more in the long term than some saved pots or gear.
