There are many reasons that people get angry. The vast majority are stupid; the angry people and the reasons. They make me laugh.
I especially find Gevlon funny when he rages over people who are people people. Rawr man, those morons and slackers are ruining your game! How else are you supposed to get your virtual sense of accomplishment and superiority over others?
Why do so few people make their own achievements? Are they so uncreative, so unimaginative, that they cannot imagine a different way to do a fight without Blizzard telling them? Go pull two bosses or tell half the raid to /dance for this attempt. Or is that no good because you don't get another achievement to lord over others?
Cheerios are awesome. Have a good weekend!
