How about adding a new page to the scoreboard that reflects overall play, and make the existing damage page 2nd? DPS: (Damage Out / Lives) - Power In HEAL: (Healing Out / Lives) + Damage Out - Power In TANK: (Damage In / Lives) + Damage Out - Power In TROLL: (Power Out / Lives) + Damage Out - Power In Lives = the number of deaths + 1. The actual formulas will need tweeking (Not sure how well Tank's Damage In will reflect performance, for example - I don't tank)... but I think it would be better to look at the big picture than just damage done...
Comepletely agree the scores need a major revamp...DPS being the first (and only) score that matters is so wrong...and idiots who rub in their dps scores when its first while completely ignoring the heals that kept them alive and the energy given them to go full bore are idiots ruining this game for others.
