It was an example,the weapon is short so that why i believe it should get a buff.
So is steel pick, bar mace, great maul and simply every weapon with blunt or pierce damage. Such is the fate of all non-cutting weapons.
Also let's not forget bec de corbin is only shorter compared to other polearms, not all weapons. It is actually a long weapon based on it's usage. Not to mention, polearms have very good power in close range compared to twohanders, which makes bec de corbin a long, deadly, superstrong, unforgiving and badass.
