Просто из описания талантов ты абсолютно прав. Ну и пруф http://wow.gamepedia.com/index.php?t...&oldid=2969769
The tier 1 Protection talent [Blood and Thunder] provides an unexpected benefit when combined with this talent. By using [Thunder Clap] on an enemy afflicted with [Rend], the warrior has a 50/100% chance of afflicting every other target with not only Rend, but also the Blood Frenzy debuff, allowing the warrior to contribute to the entire party's damage against these targets. As a tier 4 Arms talent, this is a combination available only to Arms warriors.
