Okay, so I know that you get war coins awarded at the end of each war--win or lose--and the game announces how many you get. But how else do you get war coins?
I've noticed that the war coins seem to trickle in--one here--three there. But the game never tells me that I'm being awarded these coins. I only notice by going to the shop and seeing my war coin numbers rise very slowly.
So does anyone know what other activities I'm doing that are giving me a tiny handful of war coins a few at a time? I looked for the answer on the Wiki and found nothing.
