I've had my eye on this PrE since I first heard about it. I decided that, when the enhancement pass finally came, I'd TR my acrobat into a mystic (because I already have plenty of staves and such) and test it out as a pure 20 monk build and see how it flies.
I'm just not entirely sure how to play it...
1 - Is it a melee dps? Is it a clicky-based spellcasting monk? Both? There's plenty of force/fire abilities and they do gain plenty of fire/force spellpower via the core abilities, but they also have the line of enhancements for quarterstaves. So, attack in melee while spamming your fire/force abilities for more damage?
2 - Sun or Ocean? I can't decide on which build/stance to really focus on. Going the strength/sun route would give you dps and lots of ki gain while fighting. Going the wisdom/ocean way would give you lots of ki regeneration, saves, and dodge, but take a -2 penalty to strength. I had thought of going with lots of wisdom and staying in ocean stance, getting high dodge and saves, decent AC, and trying to see if you can make mystic into a hybrid caster/melee rather than a melee that uses a few ki abilities; this would, however, lower damage output because of lower strength.
3 - Cleave and great cleave...I'm not sure about these, now. I've been playing with my acrobat and it just seems these two abilities aren't as useful as before, as they can sometimes lower your damage output due to your quickstrike ability's amazing doublestrike bonus which, if timed right, can be on you 100% of the time. Mystic has quickstrike, as well. So would it be worth going into cleave/great cleave? Stick to the THF line? TWF line seems out of place if you're going mystic. Monks (and acrobats) have plenty of attacks now without worrying about having two more that take up feat slots (and mystic gets another slot opened due to not using stunning fist).
