Scythed Chariot Question

[A Very Super Market]

Can you change the area of effect? If so, then it might be possible to better portray certain units' fear, i.e. make the spearmen's fear zone very small.

Real Cavalry won't charge a tight and ready formation, but totally destroy a scattered unit.

I don't think the "Scary unit" effect differentiates based on formation. So your cavalry would be scared even if half the spearmen were off having a siesta. And it isn't as if horses can't fight in the midst of spearmen. They just don't like to run into them, which isn't a proper allegory of the game's morale. It would also cause cavalry units in combat with other unit types, say Slingers, to get scared if a few spearmen wandered by close enough. Besides which, why would the fear effect be needed? It isn't as if cavalry have any trouble dying if you charge them straight into a phalanx.
