Not sure if this has been covered earlier - one of the suggestions I have had for CS was to relook at the rewards system/ algorithm in war. Firstly, a 5 star victory is much much more difficult to get than a 1 star victory (or for that matter even a 4 star victory) and requires many more resources to set up mercenaries, generals, etc; yet both receive the same resources in war. Secondly for a winning battle in war I typically get around 2-2.7k oil but if I attack with 3 generals, 4 planes and couple mk tanks and have some of these lost in battle (which often happens if you attack similar or better opponents, also go for a quick victory) I often end up with less oil than prior to the attack, even after a 5 star victory, that seems quite a strange set up.
