Currently it's looking like a very minor personal DPS nerf to monk but an overall (very small) rDPS buff, assuming you ran 1 caster. A notable buff if you ran 2. About even if you ran 0.

The AA nerf is rather massive (~21% lost on ~21% of your DPS). You will use TFC much more often than before, but it also hits much weaker (~28% weaker about 45% more often, so ~5% more dps from that). There's also a more difficult-to-measure loss in how often you will overcap chakra during Brotherhood, which is going to be a *lot*. Also there's potential issues with oGCD crowding during Brotherhood/RoF from all the TFCs and now TK mixed in, and Monk still can't afford to doubleweave without a DPS loss.

That said, Monk is no longer a sustained DPS job and is extremely burst-heavy, which does lend itself more nicely to playing with other buffs other jobs bring. The personal DPS loss should be more or less gone in a raid when you can line up stuff, use pots during your burst window, etc.
