Zaryhm is my favorite blue poster and has been for a long time. He kinda just doesn't take shit from people, and that's good.
The people in this game that can't play their own game without being worried about what "the lesser man" is doing has no appreciation for the concept artists, game developers, story developers, graphic designers, or their fellow gamers. Zaryhm (with his referenced 2% of the playerbase actually seeing raids and therefore all the work all of those people put into them) realized this and sent it to the poster in such a manner that he would understand - sarcasm.
You know, because sometimes to get through to a person you have to stoop to their level. And that guy probably wouldn't have given a damn if Zaryhm were completely polite and professional; probably would have dismissed it as another robot response or something else ridiculous that people come up with these days.
