I'd rather like to see some kind of a personal ranking after a wipe or a clear that no one else could see. Something simple like Excellent, Good, Pass, Close & Fail or just A, B, C, D & E if the words are too harsh. The same system could be used to show everyone the group's overall ranking so they know if they can actually defeat the encounter. As a tank I've done quite a few Odin trials and its really sad to see that many people cannot even pull more damage than a tanking tank, and on a fight like Odin most duty finder attempts end with a vote abandon because people simply cannot do enough DPS. Something needs to be done to encourage DPS players to want to perform better, and telling them when they are not playing properly would be a good start.
