But you don't see the point I'm making he just said "Delsus are you trolling" which is why I'm calling him a douchebag,
I don't think he was harassing you. He/she/it probably just noticed how bad your DPS was compared to what you should have been able to put out with your gear. And remember that there are people out there trolling, so it was a legitimate question.

Anyway, what is so bad about asking if someone is trolling? You would think he had kicked your dog or something the way you reacted to it.
