* If you're not facing wizards as foes often, I'd rather have Improved Grapple instead of Stunning Fist. My GM is letting my monk make the switch, and the two of us justify it as such: my monk has NEVER made a successful Stunning Fist, but he has successfully grappled once, even with the Attacks of Opportunity.
True. If you are not facing mages don't use stunning fist. You might as well say that mage spells are poor because no one in their right mind would cast hold person on a Cleric.
You make low will opponents make will saves, weak opponents fortitude saves and slow opponents reflex saves.
My monk has saved the party on any number of occasions by simply using his speed and tumble to run straight though the opposition fighters and stunning fist the mage.
PS. If you have 3 attacks per round and you stun the mage, then make an improved graple because of the hit, what opposed grapple roll does the mage get to avoid being grappled. The mage has just lots his ability to act, so can he stop himself being grappled ?
