I personally like the fact that under the current system only people who can recruit archers/MI know their range or even know that an SF RC produces ranged troops. It adds an element of unpredictability 
What do you mean by "only people who can recruit archers/MI know their range"? You cannot know the range of recruited troops but that is not under debate. And any noble has as much information on RCs as a peer in equal station commanding archers or MI.
