Question, since you're checking the thread - I am thinking about sprucing up the Morale system in the following ways:
1) Forcing a morale check when a unit first reaches half health (regardless of how many hits they take to get there).
2) Having variable morale checks (i.e. not all DC 15). I am thinking a range of 10-20. Taking a charge from the rear is probably more demoralizing than suffering an attack from the flanks, which is probably more demoralizing than taking attacks from two enemies in the front (for example).
Does that seem reasonable, or is the Morale DC static for a reason?
Also, is there any situation where Mass Rating might be reduced in combat? I am thinking about getting rid of it in my Excel stat block and just adjusting the formulas in each cell that accounts for MR.
