Monk – Drunken Fist Stance has been altered. The damage bonus has been slightly increased, 5% parry chance and a mitigation penalty have been added. The increased hate generation has been removed.

I have looked at this for two levels and noticed that the 5% parry chance is not altered when using this stance.
My parry chance % remains untouched when going from Drunken mastery(the dodge % does drop tho when i switch).
