Hi! I played more than 1 year ago and i have some suggestions:
Spectator Mode: This tool would give a new air to the game, since it would be possible to watch friend matches and transmit them in the case of leagues that take place worldwide.
Club or Clan System: This tool would allow competition worldwide, throug leagues as it is won. It would also make it possible to publicize the beast teams in the world and encourage competition.
Hándicap nerf: It is really frustrating to be playing important games and to benefit the player with less level advantages in a abusive way. Keep in mind that to be full max players requires time and work, therefore it does not seem correct to me that the game is so impartial. It shows when game will let you win or lose, it should be more partial.
I hope to be a contribution and that you read me, greetings!
