Will throw my hat into the "agreement pile".

I've been able to focus much more on boss mechanics, while figuring out an optimal rotation and it's far less stressful. Moreso than my Samurai. Also like feeling helpful in content by using Brotherhood and Mantra.
What I'd like to see 6.0 onward:
--Another Chakra ability, but not as potent... a Chi Blast that consumes ONE chakra stack. It'll be our long range ability to use if we have to make distance but want to add a little uptime.
--On the subject of Chakra, maybe have an ongoing fiery effect when you have all five currently. It's cosmetic, but would look cool.

Other than that, this new MNK is much more fun than I've imagined.
