I agree with this. Furthermore, I would suggest making it visible to the whole party. Why? Because it would spur rivalry and competition between party members. As a tank I want to beat the other tank into the ground, same for when I heal or dps. I hope my fellow party members feel the same. Promoting this mindset would improve player skill tenfold and make the community healthier as honesty would be allowed to flourish instead of barely held back distain of our current ways.
