Pack luck
I have notoriously bad pack luck, especially when it comes to big promos like Thunderstruck or TOTY. I'm sort of saying this to complain, but mostly I'm saying it to tell people that you have to expect it these days if you want to continue playing.
EA have no care about people that only spend £100, £70, or cheaper to buy the game. They only care about their whale players and streamers spending loads of money, it's obvious by the probabilities on store packs. While I agree that spending money should give you a good chance to pack these cards, I think it's despicable that you have basically no chance if you don't spend money.
I don't want people to think I'm trying to tell them what to do, but find other games to play, or do something else with your time. I know we play the game because we love football and it's hard to not play this game, but all we will do is frustrate ourselves or give in to their push for everyone to use the store.
