the main statistic “melee physical damage” does not apply to two-handed weapons (and I tested in games I do not do more damage with more powerful weapons its even the opposite for most weapons )
(it is impossible for me to add screen shots on your site)
Edit : I try again but its does not want to join the screenshots (jpg). but its not serious it would seem after having discussed it with other person that (perhaps) it is me who badly understand the operation of the statisque. Can close, delete the topic if you wish. sorry for the inconvenience if i ever got it wrong.
