Why would you hate being able to see if you are doing well or not in a fight. If you wishfully want to stay ignorant about how well you are doing in a fight then so be it but when you work with a group of people on end game raids like savage, you need to pull your weight.

Example, if you do okay dps and do your job just fine, but someone else same job does exceptional dps and does the job just fine, majority will take the one who can do the exceptional dps. because as long as you know how to pick up and learn mechanics for fights, you can always improve dps, but if you lack in both mechanics or dps, your going to be dropped for reasons.

Just like in real life jobs, if someone who works meh, okay, doing what they are supposed to do. The store isn't always clean but it looks okay, and then boss hires someone who does exceptional work, workplace always clean and does what they are supposed to without wasting time, who are they going to fire in this situation without exception?
