Monk Needs a Complete Rework

[Ultimatecalibur]

I am not a Monk main at all, so I am a little bit confused with one of the changes.
Can anyone clarify what Form Shift does now? Sounds like it is just basically a 7th stack of Perfect Balance? Or is there something I am missing?
Does this not apply for weapons skills used during perfect balance : "Any additional effects associated with the executed action will also be applied." ??

Weaponskills done with Perfect Balance stacks will not change your stance while Weaponskills performed with Formless Fist will change your stance.
