читаем описание спелла:
Возможно проблема в том что сзади все скиллы прокают, как в патче 3.0.8, а сзади уворот или пари не пашет.Patch 3.3.0 (08-Dec-2009): Now also increases the chance for ranged attacks to miss the hunter by 100% while under its effect.
Patch 3.2.0 (04-Aug-2009): This ability now allows the hunter to parry spells and attacks from behind as well as in front. Now has a new visual spell effect.
Patch 3.0.8 (2009-01-20): Design changed to grant 100% parry and 100% chance to "deflect" spells coming from the front, but prevents the Hunter from attacking. Lasts 5 sec. 90 sec. cooldown.
