I know it's not a crucial thing, but still, I suggest creating more unique visual decorations and modifying the profile UI to showcase them. Offer vehicle skins that can be purchased or earned by participating in battle pass events. Include avatar frames, rewards, and achievements on the main profile page. Perhaps allow players to change flags (from a unique list that can be expanded through in-game progress and battle passes). Take a look at Wild Rift and other skill-based games that use visual decorations for monetization without affecting gameplay.
Yes, this would mean additional work for the design team and some deviation from historical realism. However, it would also provide an extra source of revenue and, importantly, increase player retention.
