I actually thought of making the same suggestion, it would make mobile archers a lot more useful. As it is now they rout to any number of different provinces and its a pain/disadvantage for using hit and run tactics.

But maybe this is WAD: think of how easy it would be to have constant skirmish battles where you have, say, 40 crossbowmen fire off a damaging volley and flee, arriving intact in a neighboring province only to repeat over and over again.

My suggestion would be to give (if possible) this ability to retreat+reform only to FAST archers like horsebowmen and maybe some fast skirmishers but not to every unit and certainly not to mages.
