Meh, I don't see why they're so controversial here. Tanks are measured by how well they generate enmity / take damage, healers are measured by how well they keep people alive, so why shouldn't DPS be measured in some way? I understand that some people will use them to treat people negatively, but imo that's not reason enough to stop the people who want to use them constructively.

I wonder if SE is also worried about class balance issues becoming a persistent new problem should any one class dominate damage meters over the others. Seems like it could be another thing for the playerbase to stir an uproar over should it happen.
