Fidels Slower Combat 50%
This will increase the time it takes to fight battles by around 50%. I have put every effort into trying to maintain balance as close to vanilla as possible. I took notes from all the standalone combat mods and put their ideas into this mod so as to achieve what they have done but tweaked for vanilla balance with a solution that is simple and elegant.
This mod does not modify unit tables
Thanks to everyones work below which provided insight into the methods used to go about the problems:
