For the stats i'm building my monk around Deter>crit>SS.
As long as i can do every spells i need to during my Perfect balance,i don't think i need more SS.
Ofc,on a long fight without interruptions,it would be better but there is no fight like this .

For the rotation i think you already know them ,just don't forget to reset your twin snakes and dragon kick when they're about to fall off.It's really important,missing one or two won't be too much but missing a lot will reduce your dps.

And ofc,it's worth to use your DOT(touch of death)and having fractuce is good aswell.Sometimes it's really usefull when you know the boss is going to go away for a while so you can put your dots on him before.But if you can just hit him without too much interruption,touch of death and demolish are enough.
