Why are low standards for dps acceptable?

[Lego3400]

Damage meters are against the ToS because these are 3rd party software which is data-mining.

For the second part of your statement. How much fun are you going to have if the boss doesn't die? If the tank doesn't tank more than one mob. If the healer heals only the tank? Some people have fun while wiping and trolling - shouldn't they be allowed to have fun?

There is a huge diffrence between "failing" and "not doing well enough for someone else's arbitrary standards" No one will disagree trolls are bad. Nor will anyone agree wipeing all day is fun. But if you can down it, that's all that matters, not the actual numbers.
