On the final point, when the Soviet’s capture the Reichstag, have the process of the flag being planted move in sync with capture progress.
Maybe even a 5 second cutscene of a squad planting the flag, perhaps the top player on the Soviet team.
You could even have the German forces “surrender” upon the points capture, and the Soviet team could finish the game by completing an animation to plant the flag.
It’s an iconic moment, and I think it deserves a special mechanic of some sort.
(Yes, I understand the flag was planted and then removed originally, and then planted again after German defenders were taken care of, but come on. Shits cool.)
