Possibly one good idea on how to accommodate for players looking for a casual time vs players looking to hardcore grind could be re-evaluating and adjusting the dungeon prefixes and giving them larger amounts of difficulty, in turn giving more EXP as a result, vastly more than it is currently. (Each prefix adds about 5 or 10% more EXP from monster encounters for example.)

For example, in a giant dungeon the area you explore is much much bigger, you could also give a special tag to monsters which makes them actually giant, increasing their Strength and HP by a larger amount, this sort of dungeon rewards 25% more monster EXP.

Stylish Dungeons could have rare monsters that activate their own form of demon translation, granting them access to boss skills usually not used by them.

Mixed Dungeons could have any monster appear in any fight, so you could possibly have a wings of fire appear with a grindylow in the same fight.

Right now the grind process is getting to 50 or up to 55, then abusing percentage EXP all the way until 60 as its clearly the best way to grind, monster exp doesn't come close at that point.

Stuff like that.
