Chasing routers

[RLucid]

But feigned retreats and routs are a time honoured tactic.

So I think being able to merge/split the tactical formations makes sense, and solves the 20 unit limit problem. Think, no more worries about what the AI is going to do with your other general.

In another thread on this topic, someone mentioned Arcani. Indeed they can be rather amusing inducing a rout by their surprise arrival, without actually making contact, and then totally slaughter a superior unit, once it turns tails and runs.
