Another perspective Greg is to reduce the minus modifier for Retreating/Routing to -1. This would mean ALL reduced Cohesion states would carry the same modifier -1 (SHAKEN-RETREAT-ROUT)
I have been considering this in line with comments from Steve about how difficult it might be to Rally routed troops particularly Horse who have committed their entire brigade to a close combat and lost. This would mean that the chances of them Rallying would depend on:
Throwing a 6
Having the C in C and/or Brigadier attached.
This is again down to a decision on what one is trying to create:
1. As much realism as possible
OR
2. Fun based on realism!
My instinct is that the former is rather po faced and that the world we live in needs more fun
What say you Funsters out there??
