Atm my build level 32 is 21/18 6WM    124 Wpf in throwing and 116 Wpf in polearm.
I haven't read everything, but if i understood correctly, in the next patch you won't lose wpf if you have 6WM, unless you play an hybrid build.
With my current armor i need at least 124 wpf in throwing,  could you please tell me how many proficiency points i can put in polearms ( or another spec) after the patch?  
Nvm, fuck that, time to go full pole with 7 WM and IF  * plus heavier armor and 7 Athletics
