Maladath useful on Humans?

Hello fellow Rogues.
So my Guild and i had a discussion about Maladath, Runed Blade of the Black Flight and if it's useful on Humans or not.
It has been said that +10 Weapon Skill (in this case Sword) is useless since that +10 Weaponskill is "cap" and more over that number is useless.
As we know, Human racial gives +5 Weaponskill on Swords, with the Combat Talent Tree we get additional +5 Weaponskill and with Maladath, we get ANOTHER +4 Sword.
So we're at 314 which seems useless if its true that +10 Weapon Skill is cap.
Is this true or is it working different? I know Human Rogues kinda have different BiS weapons than other Races, yet i still see a shit ton of Human Rogues with Maladath and i just can't imagine they all simply forgot about Human Racial and the Weapon Skill cap.
Thanks for your help.
