I agree with the premise of this answer; DPS meters in battle could lead to discrimination or harassment.
Perhaps functions could be added to the existing striking dummies allowing players to check their own DPS output while not in battle. Maybe, instead, create a special dummy that can be placed on estates that has this type of functionality. This would help players improve themselves and try out new rotations/strategies. This adjustment seems like it would fit in naturally with dummies since they currently serve little purpose.
I would love to hear a dev's thoughts on this idea.

Update: Cool! Looking forward to see what they come up with!
