Patch changes

Patch 9.0.1 (2020-10-13): Removed, replaced with [Rupture]
Patch 7.2.5 (2017-06-13): Nightblade now increases your damage dealt to the target by 15%, with damage over time component reduced by 35%.
Developers' notes: Further pushes Subtlety away from maintaining Nightblade on all secondary targets and instead into focusing their damage into 1 target. Additionally, gives Nightblade a mechanical interaction with the rest of the core rotation that fulfills the "setup" feel of Subtlety.
Hotfix (2017-01-31): Nightblade/Night Terrors now reduce the movement of targets by 50% (was 30%). The reduction remains at 30% in PvP situations.
