"If you're looking for a class that allows for serious customization (that you actually control), especially on the fly, shapeshifter probably isn't for you."

a) ANY shapeshifter form becomes totally useless vs ANY noob with the polearm (tested on 6 different 1st tier form). Maybe there is a form that can do something vs polearm, but I am unaware.

b) Fumble is not an option vs battle or vs nodisarm/noremove weapons.

Are you saying that whole shapeshifter class must be totally rocked by anyone wielding a polearm?

That's nonsense. There must be a way to at least increase chances and not losing 100% out of the 100%. I just didn't find it and thought maybe someone have an idea, but your ideas are pretty useless, no offense.
