Is there a minimum distance at which the rally superpower is effective ? Because it only works about 1/20 times, so I got a habit of chasing my routing units with my general and only blow the horn while very close to them, to make sure they hear it . Needless to say, this requires micromanagement, so I wanna know if I'm being dumb for doing this.
Is there any way of increasing the effects of the horn blow ? As it is right now it's almost useless, basically in the same bucket with other "features" like wedge formations etc.
