New glyph of concussive shot in PvE?

So now in 4.0.6, Glyph of Concussive Shot is going to limit maximum run speed.

I understand this can be handy in PvP to deny some sprint abilities from players. But what about PvE? What kind of mob ability this new mechanics will affect? Can this, for instance, deny those boars to charge, or those nightbane worgens at Duskwood to leap at you from afar?
Ok. So basically this glyph will become completely useless for someone who does not PvP?
