We've all heard the "50 DKP minus" guy (it's become nothing less than a WoW classic), but imagine if all of that took place inside a chat channel, and you've got this (a lot of the text is not safe for work, if you aren't supposed to read cursewords at work) A more stunning display of angry raidleading I have never seen. This guy has more ways to say "you suck" then there are to actually wipe a raid.
And that's why it's so great. I think my favorites are "this is MC level sh*t," and "I don't care how you did it in your guild-- your guild sucked, that's why you're in my guild." Seriously, almost everything on this page is comedy gold: "Just pull and let god sort it out." Dives was funny, but I think Sebudai is my new favorite raidleader.
