So, my raiding group has a melee roster that's starting to feel pretty bloated, but no WW monk yet and we have one interested.
I've leveled a monk to level cap enough to know the basics like a fantastic AOE stun, a fair bit of mobility for a melee class, but I'm nowhere near invested in the class enough to know what they really bring to the table in terms of raid utility like DK's bringing grip that can be used to great effect on some fights like Gorefiend or Xul'horac, or Rogues and their novel abilities to handle things like runes on Kormrok.
Do WW monks add much to the raid beyond the obvious?
