Please reduce data usage if possible. I can only use my limited mobile data plan because I dont have wifi. Im not the only one, maybe there are people like me too. The game is so amazing tbh. The only thing that kills my enjoyment on playing the game is its data usage. Help us please :(( thank you!

I think it's impossible to reduce data usage unless you set your graphic settings minimum. Maybe that doesn't change thing a lot, but I quess it help.
I've unlimited data usage and I even download everything using mobiledata. In Finland all operators offers unlimited data for reasonable price (exluding prepaid). I've unlimited 150Mb/s+unlimited calls/txt messages 29,90€ month and that's enough for me.
I hope you'll find solution to enjoy this amazing game.
