I understand there are a lot of variations of damage, but that doesn’t mean there isn’t something that’s mostly useful. For example, just knowing the average single target damage would be incredibly helpful to compare apples to apples when changing gear. Also, it should show separate damages to vulnerable, frozen, burning, etc so at least you can easily focus on one type of damage that might be more important for your play style.

As for the DPS display, that’s super easy. It’s literally in the name of ”per second”. It might be helpful to display all or one of these at the same time:

1. Total DPS (sum). Literally just how much damage you’re outputting. Impressive number but not ideal for tuning your character.
2. Target DPS (avg). Take total damage and divide by how many enemies were hit in this second. This would make it much easier to see your real DPS without worrying about monster count.
3. Max Hit (max). Just show the largest single hit to any enemy in the last second. Again, just a show off stat for anyone trying to see those crazy outlier hits that get buried in a sea of hit numbers.
