The suggestion would be to change the logic and treatment of calculating points (which consist of the player’s actions) after the battle.
Usually it is a person who drags the rest of the team on his shoulders and they build rally points, destroy tanks, and stay on capture points (or several players), and of course they are rewarded with different battle hero reward badges for this.
It’s nice when this happens, but there are cases when a person who built rally points, and for example his strategic logical game was a key factor in victory - he gets the corresponding badge, yes, but remains at the bottom anyway. And no matter how you look at it, the first place will still be the person who collects the most kills. Even if they used the most squad slots, and did nothing else, but simply managed to withstand the point with their squads with the help of the infrastructure created by that other player. “Win is win” you can say, but who was the real “squad mastermind”?
So, some specific suggestions:
Depending on the battle mode you get (Conquest, Invasion ect.) the best players after the battle are determined by how much they played the mode itself, and used the right tactics needed to win in that particular mode. Not the overall actions. - So in the first place, for example, would be a player whose strategically placed rally point was a key aspect of victory, but he may only have 12 kills, and a person who has 112 kills, but did not contribute to the strategic game of the mode, remains at the bottom.

Because this automatically goes to suggestion number 2:
that kills in this game would be counted based on whether it is squad mode or lone fighters mode. I suggest making it so that in squad mode, 1 frag counts only after killing one soldier from the squad, for others you only get additional xp. Because in lone fighters it is counted from the killed player. So it would be more fair, where the real victory would be determined by the good use of different specialists according to their functions.
In other words - we have a game like Enlisted, where the main sell factor is squad strategy gameplay - but at the end of the day, it’s still just an arcade fps shooter, where the one who scores the most kills wins table still. I think that needs to change.
