What does a Monk bring to a raid?

[Noselacri]

Pulling and pretty good DPS. You shouldn't need to use a monk for tanking on a raid, but they can off-tank trash and such if necessary. Then in Velious they become good rampage tanks and such. You'll always want at least one monk on any raid, preferably two or even three if something happens to the others. More than that is just sub-optimal DPS, but then you can't exactly bring 20 rogues.
