Just a small suggestion to increase the money drops, 4,8,9k.
Atleast for premiums, I don't know about you guyz but I an paying for extra money I know u DEV's don't want this to be a pay2win but the money drops right now are terrible. It takes me about 200 zombies or more atm to get those high money drops.
My suggestion is not to higher the money drops, just the drop % of higher drops like 4,8,9.
