Thumbs up for ingame parsers!
Being told my numbers for the first time by someone in the group made me strive to become a better player. And its really helpful when testing out rotations. Just seeing my own numbers would be enough, I don't need to see those of others.
And before anyone comes with the SSS argument again, this does NOT help at all for comparing rotations and it's got nothing to do with actual performance in a real fight, where you gotta maximise your dps with mechanics happening.
