Monk Epic Fist... is it REALLY that good?

[Kutsumo]

Redid my testing with more mobs and going by average hit instead of DPS (since pulls and laziness on runners can skew results).

Fist mainhand (9 dmg bonus at lvl 52): avg hit of 29
AC mainhand (9 dmg bonus at lvl 52): avg hit of 42

This comes out to roughly 8% difference between the two for me. That difference should continue to increase as the damage bonus goes up. However, one might wonder if it's worth keeping AC in mainhand when soloing or tanking b/c of proc and slower delay for less ripostes.
