Would you like an in-game parser?

[KarstenS]

Plenty of people can tell when you're playing incorrectly, even without a parser.

When they have that time to watch what others could do wrong in their rotation, they are not focussed enough to do their own job. I did already see some of them and I am clueless what they are able to see, as their own performance was far away from knowing how to do the basic rotation of their own class correct.

(I do not mean 100 DPS less. Its more about 50% and less)
