My suggestions for improving the game:
1. Revise the glabol battle.
1.1) There is little from the player in the zivset in this battle, so there is no interest in participating in it.
1.2) A new faction has appeared, but the battle is between the three factions, not order ...
I propose to do something similar to the Word of Tank in the game. Add the ability to create clans that will fight over territories to show the greatness of the clan and get resources.
2. Remove the features of the characters, leave only the personalization of the characters. (Character traits overload the gameplay complexity too much.)
3. Interface.
3.1) In the main menu, add the ability to scroll in a circle and up. Now you can only scroll down. (I play on a gamepad, there is a function I need.)
3.2) During the game, add the ability to exit to the main menu or exit the game (This is how it should be by default).
3.3) Add the ability to re-select a character during character selection. (There are miskliks.)
3.4) Speed up the loading of the match. I'm not really into software development. But why not make a parallel loading of the location, during the selection of characters ...
