Woreczko,

That actually sounds about right. I have to use rather massive mount modifiers to get spears to be effective vs. cav, and to make horse/camel/elephant matchups make sense. I usually end up adding 4 to 8 total in adjustment to the existing values.

In RTW the range of the attack defense numbers seems to be wider. If you want a noticeable impact you need about an 8 point delta or more, at least with the units I've adjusted so far. This was particularly noticeable with elephants I reduced elephant unit size in half and hitpoints in half as well. This works about like I want it vs. infantry and skirmishers, but the stupid cav were killing elephants with the base mount modifier values (probably due to the massive charge bonuses.) I had to move it 8 more points for a total delta of 20, and I might need to move it more. (With the smaller hit point count and unit size I will probably have to increase the elephant "momentum" factor so that heavy cav doesn't stop an elephant charge. I don't think this is combat modifier related, but more unit size and relative momentum factors.)
