I have an Austrian army so I have my fair share of "challenged" commanders. I always keep them in the thick of the action but worry a bit about the proposed rule to force others to do the same. I was thinking instead of decreasing the CinC;s command radius that we try something more along the lines of.
"Sub commanders must attempt to remain in command radius of at least 1/3 of their units rather than 1 unit as now"
This would mean that Sub commanders could release some of their troops to the CinC but in practice they would usually have several units with them.
Also
"Units must use their own Sub Commanders abilities over the CinC's abilities if both are within Command radius"
This would hopefully keep all of the Commanders involved in the game.
Any thoughts?
