I'd be happy and excited at a self only damagemeter with a obfuscated value. Basically some kind of random seed makes the number unique to you. So you can see when it's higher versus your own previous performances but there is no way for you to compare you dps to that of your neighbor as their scaling/seeding would be unique to them. That way you get the important value of being able to tell what builds/rotations work to optimize your performance but there is no epeen macho alpha dog rituals going on in every pug dungeon run.
