Dungeons are always a grind but I feel like if you added bronze, silver or gold medals to them it would make them more enjoyable.

The criteria of each medal could be as follows:

Bronze:
Complete the dungeon in a certain amount of time.

Silver:
Complete the dungeon in a certain amount of time(less than silver), players cannot get hit by certain boss abilities (AOE, or things on the ground)

Gold:
Meet both bronze and silver criteria without dying in the dungeon at all and must complete in a shorter time than silver.


Rewards for medals could simply be cosmetics.

This could be expanded upon to include both trials and raids. Achievements for completing things obtaining medals as well.
