Playing the Whites, I need to allocate replacements for six different nationalities, with approx 5-15 unit types each, so I currently have 50-60 replacement options, ( and with currently only 60 conscript companies at my disposal, I could realize for maybe 6-8 of the available 50-60 ). As a consequence most of my units will get no replacements at all!
I think this is one example where the replacement system in AGE may not work well. Could this be simplified a bit? For example, why can an artillery piece bought for the Southern Russian Army not used by Northern Whites or Don Cossacks?
