Unbalanced as in the low level producers dont give enough incentive to upgrade and syndicates are the key. you need to come up with 1,000,000,000 X upgrade or something for low level producers
when you add 1 billion dmg to your taps how much does it really add? you should show the mulitplier if not we never know if it is worth it to buy the upgrade
You can get 3 stars for all levels without spending money so dont bash it becasue its a casher game. Furthermore you get ivolve points for logging in every day. I believe this system works the best so that patient or poor gamers can complete without spending money and impatient or people who want to support the game can spend money. Win Win for all
