I didn't say the Mod was too powerful, I can't make that determination without playing it. But lets just take a couple of examples for sake of balance.

LC have Lesser Fear -4 (Or is it Cause Fear?). This is normally reserved for supernatural or blessing effect units.

LC are not capital only or sacred. There is no limit to the LC. That means potentially you could create entire armies (if resources/gold permits, and with your current costs, that isn't hard) of just LC all firing arrows and if they are engaged bring their fear into effect.

No Sacred unit that can get a Fear Blessing has archery, they all require movements to engage or be enganged, they can't sit back and pepper them with arrows.

Imagine either Wind Guide and/or Flaming Arrows (especially flaming arrows for penetration) with only LC?

Also imagine playing your new BK vs Ulm, who have virtually no priests?

These are balance issues and not at all inclusive of what is 'real' or 'historical'. Also there is no way to represent the fact that your LC lose their horse or any other effects which they suddenly lose their quick striking power and become weak, badly armored footmen.

All of these considered, fear is a bad choice to give for an ability and Awe is more in my mind both balancing.

I feel that it's important to take into consideration when you are making what you consider 'a more balanced ...etc' different playstyles. Not only those who like to spend points on pretenders but those who spend them on scales, and those who wouldn't build 'standard' armies and build only single units in order to see the effect. I would think just adjusting the defense/attack would be enough of a simulation of the quick striking and feinting of the LC and you wouldn't have revert to going to special events.
