Honestly, this is an amazing game. We love to see more improvements to the game. And I think we all know what one of the main ones are. The Lack Of Players.
As I would like to suggest to the developers of the game, remove the rental servers, and have it so you can make custom servers available for every player. Another part of the custom servers that we would like to see, is the introduction of bots. Even if there aren't many players, we can still keep the game going with players playing with teams filled with bots/AI.
We just need something done about the player count, and I think this would be a great idea.
