agility should give you bonus pursue, the ability to push your way into enemy's and force them into combat positions

mana should give you bonus flee, the ability to continuously maintain your pace and escape through keeping yourself moving

That doesn't fix it alone, but it provides a buff to mana that isn't going to make the DR stacking invulnerable Xomac Hatsune "impossible to kill" builds come back.

Not a huge fan of this, if only because then virtually no one can ever successfully flee. (Apart from the really cool original mana stacking people.)
