Why are low standards for dps acceptable?

[Kallera]

I personally have the most fun when I see a group get together and be awesome. Nobody is asking for people to be perfect, we're just asking for effort. Where this argument falls apart is it assumes the fun of one person outweighs the fun of the other three people. "I use a poor rotation, but it's ok because I had fun. Who cares if the other party members were upset?"

The OP got voted out, so clearly his idea of fun was not outweighing the opinions of the other members of his group.
