Honestly they should show the dps/heals/damage received at the end of every duty. I remember enjoying seeing how i did back in DCUO when thry showed the party's numbers at the end of the instance. really showed me when i went beast mode and when i was doing low. it really helped me improve myself and my gear. i know not everyone enjoys seeing those numbers but it would really solve the whole act issue. if they do implement this they need to fix/improve their report system to counter the toxicity that will come.
