Reaper's elite skill "Chilled to the Bone!" apllies an incorrect amount of Quickness on melee hit.

[Elldar.1647]

With the new balance patch, Chilled to the Bone according to the skill's description is supposed to give 10 seconds of Quickness per melee hit, however, in practice it only gives 5 seconds of Quickness.

Not certain whether the tooltip is wrong or if the skills itself doesn't work as intended, but it'd be appreciated if it got fixed, regardless.
Thanks in advance!
