Thanks Dol Guldur & professorspatula. I'll get that 4+ fixed, apparently a leftover from the modification.

professor, thanks for the info on kill rate, etc. I had modified the kill rate with the simple double-HP change, but I had not seen this sort of thing happening, so I assumed it was because of the morale changes that I was seeing longer battles with more interest in how they played out. With your info, and searching around a bit more, it does appear that the kill rate is considered the affector of this rather than morale.

So, mistaken conclusion. Everyone can go about their business now, nothing to see here.

Oh, and Dol Guldur, I haven't tested it with any factions besides the greeks, roman factions, parthians, and carthaginians. I'll have to get up north sometime soon and see if the berserkers are a bit over the top.
