Intimidating Shout Nerf.. why

Intimidating shout is a warriors only quasi cc.. oftentimes coordinating a well timed fear on someones healer is the only way for a warrior to get a kill in pvp nowadays and for some odd reason you choose to nerf it from the already low 10 yard range to 8. Isn't this ability already lackluster enough with the long cooldown and the fact that it breaks on a single point of damage.
