Вот ты поспорить то любишь.. И главное источники своих цитат не даешь...
Patch 4.0.1 (2010-10-12): Removed.
Patch 3.0.2 (2008-10-14): Can no longer trigger more than once per 6 seconds.
This removes the possibility of Sword Specialization procing off itself.
Patch 2.1.0 (2007-05-22): This ability now grants extra yellow attacks instead of extra white attacks. It also grants rage based on the speed of your weapon. This change will make Sword Specialization no longer reset the weapon swing timer when it triggers off special attacks, and results in a net increase in damage dealt.
После начала БК, прок от специализации на мечах стал желтой атакой.
