I think it's because bad and insecure people tend to flock more on the dps class. It's really controversary though; why play a dps class, if you don't want to do dps? Apparently it's okay for the bad dps to semi-afk while watching hentai somewhere.

This game goes massive leaps and bounds to protect dps ego anyways. No parsers (party or personal), no tp bars shown, calling out the need to improve=harassment. It's really sickening.
