Why are low standards for dps acceptable?

[Andrea]

Yes I'm serious sweetheart.

Then if thats how you feel I hope I honestly never get paired with you in a duty.

You literally said that doing more damage is optional. It isn't...you're a DPS when you sign up for a duty you do as much damage as you can. That is impossible using a 50 rotation. Your logic is completely flawed.

How would you feel if I as a healer just wanted to afk behind the tank and let my fairy heal? Obviously any sane person would have a problem with it.

Anyone who actually uses your logic in a duty with other people is indeed rude, bad and lazy. "lets not try to do as much damage as I can, let the other people carry me..."
