Our raid leader is running the addon Failbot. It reads out loud every players name that gets hit by an attack that you should be able to avoid if you know what you're doing.
For example, if I'd get hit by Shadow Crash in Ulduar the raid leader would automatically post: "Niniel fails at Shadow Crash".
The point of the addon is naturally to see if someone fails a lot and discourage them from doing so. It can be sort of a morale killer though because it's not fun being told you fail over and over and mid-raid a few people complained about it. That's why I suggested in /o that the raid leader should modify the .lua file of the addon into something positive instead of the words fail. Everyone knows you've failed anyway so you don't need to be told just that. The officers laughed at my suggestion and the RL logged out to fix the tweak immediately.
For the next pull the addon read out "Player X is incredibly awesome at Shadow Crash". This got reactions like "new failbot ftw!", "lol @ praisebot!", "Successbot ftw" and the raid leader happily stated "No longer a morale killer! Fail in style.".
Oh, also I haz 4 pieces of T8 now, woot! Basically the Shaman 51 point resto talent as a set bonus and with no CD.
