Improvements to the buildings of the City of the League:
-I want to suggest you add a button to improve the city buildings of the league.
-That the team members and the leader can activate the improvements in the city of the league, either level 1 or monument.
example:
+ 10% repair speed
+ 10% of hp recovered when rebuilding
+ 10% field of vision
+ 15% reach of the turret
+ 15% attack against aircraft
+ 10% attack against infantry
+ 15% attack against armor
+ 15% attack against vehicles
+ 15% attack against battleships
+ 15% attack on ships
-I suggest this since there is an equal button in the improvement of each player's buildings.
