I've made the suggestion before, but what about an after action report type thing. I haven't done PVP in a long time, but after each match, a window would pop up with all kinds of data like dmg done, dmg healed, dmg reduced by cooldowns, stuff like that. That may work. If I'm a DPS and dead last for damage done, then I know I have to up my game. Make the data sort-able too to make it easy to read. Of course, this only matters if I choose to improve myself, nothing is forcing me to ignore all the data points to keep sucking. /shrug. Quite the pickle.
