Injecting this update in the game must not be intended. Many people don't like to play matches with stars, WHY the game need to force them that.
Another thing, I bought many packages from the store before related to Bux & Gems, so what will be FTG decision in returning back our money since no use for money now for me. Additional to that, if people don't have bux, how will they upgrade their players, FTG will force them to buy packages to get bux for that upgrade (L9 to Max is 100,000 Bux). Not everyone have the ability to buy stuff from the store.
Also, giving your captain to friends to assist you with Bux in higher arena will disappear, so many good relation which was built because of the game will disappear.
FTG need to review this decision.
