Since the patch then the patch take back patch (Grins) there has been an issues with social agro with mobs in some zones. In sleepers specifically, you can sometimes pull right over another mob of the same type and still not agro them at times. Not sure if the radius was decreased by a tremendous amount or what was changed exactly, but something is definitely still in effect.

Nothing was changed with aggro radius anywhere, I'll catch you online, see if I can see what's going on.
