...Weapon shattering now looks at weapon proficiency,...
could it be possible its not only related to the proficiency but with ne minimum requirement of the weapon? I shattered 3 blackstar swords in less than a week... I have 81 thrust.. the minimum for such weapon is 80.. but 81 is still high as proficiency .. so the new system consider I need more training with thrust to don't shatter blackstar swords or 81 should be enough and considered like more than skilled in a thrust weapon?
I hope I make it clear for you.
