Battle Changes
Due to extensive testing we were able to track certain parts of the battle engine that did not work as we wanted to or thought that we do not have sufficient control:
- Hit chance. This value is calculated like this: (Melee Attack + Base Hit chance) - Melee defence = Hit chance. Final value can't go below minimum hit chance and above max hit chance. This meant that before if a unit had 40 melee attack (so around elite status), 15% base hit chance and was attacking a unit of medium quality (60+ defence), the overall calculation was 55-60=-5. As you can see, this meant that pretty much most units would get negative hit chance. But, since minimum hit chance was at 10% no matter what, most units would hit that 10% most of the time, meaning that overall melee and defence stats did not matter (And also explained why falx unist were that good as they were able to hit above 10%).
- In new stat system, minimum hit chance got lowered to 5% while overall unit melee attack was increased and melee defence lowered. This means that unit stats matter a lot more.
- Overall defence, while lowered, matters a lot more now as the values rely more on personal defence than on shield defence as before. Due to errors in combat calculations, shields seem to be also included for flanking combat and were not affected by fatigue, making an exhausted unit not that much of a weaker target.
- Flanking and fatigue are much more important as the penalties for them are applied correctly.
- Cavalry charges should work better and be more consistent as their hit chance and damage will be correctly applied
- Certain units, especially those with small shields and with two handed weapons, have good starting defence but since personal defence skill is lowered by fatigue they tend to suffer more than units with good shields. This means that certain shock units will be very good at early stages of combat but if the line will hold, the roles might reverse.
- Units of marines slightly nerfed, few slightly buffed.
-Added Formation Attack to some Roman units (For testing purpose, not yet added for all, please report how it works) - with changes I made in past few months Formation Attack seems to behave a lot better
-Added more realistic spacing for most of ranged infantry, overtime it will be tweaked to be more unit specific (like some being more disciplined, some in more spaced out order), please report how it performs

Reforms Fixes (thanks to Litharion!)
