We don't? Why? Isn't it working as intended?
Not working as intended? Whatdid Relic actually promise with this feature? Good that you ask!
"The expansion's armies add new strategies to COH2, and play significantly differently to warrant investigation. But I get the impression Relic is more excited by the addition of War Spoils, the new content delivery system that it hopes will fuel the game's success in the future."
"War Spoils gives you rewards after each game, including commanders, skins and intelligence bulletins. You can pull three commanders into your loadout before the start of any match, but you can only unlock one during a match. The intelligence bulletins are passive buffs, such as "reload faster". You can bring three of these into a match. The skins do exactly what they say on the tin and make your vehicles look prettier."
