We have reports in our mail regarding each battle that takes place. This is helpful for a number of reasons. I think it would be a good idea if we received a final report in our mail that states total loses of each troop type, the number of troops saved through the first aid skill and also the total amount of recruits received through the Hostile Takeover skill. Then a final tally of troops lost. Or something along those lines.
Having this idea in the game could help players work out easier which and how many troops they need to train in order to keep a good complement of certain troop types.
This could help players with a low population count or for players that do the same adventure over again. It could also save time in the barracks as people would know the exact number of troop types they need to train to recoup their loses.
