I really don't see how people still think MNK needs an improvement. Especially with Brawny's on the AH now, my Blue Proc MNK is better than my other better geared, better macro'd jobs at tanking, DDing, and the massive difference in HP means that anything with a big AOE doesn't 1-shot my MNK where as many of my other jobs will go down (especially being a Taru).
I can't help but think that a fully pimped out MNK would beat a similarly pimped out WAR in most situations, especially since the WAR would probably end up dead.
