BOE Belt n Boots have better stats for less item levels, and easier to get (if rich or really lucky with drops).

Us monks gotta stick together! But I doubt I'll be playing mistweaver anytime soon...

Wow, your Mastery weight looks even worse than mine.

Even though you might be the only MW in our raid, it's great to have this information easily available. If I get time in Asia, I should write one of these up for balance too.
