Raid

The group activity of slaying dragons and unicorns for the greater good of collecting purples for all involved (but mostly just for Shadowalker).

In vanilla WoW a raid was typically made up of 40 people for most end game raid instances. Because of the sheer amount of people in said raids there was much "wiggle room" for the shitty players, and you were usually still able to win despite people doing stupid things.

In the expansion, The Burning Crusade a raid is typically made up of 25 people and has a greater focus on the individual not fucking up.
