Look if it's sbc players then we maybe don't need them, especially with the amount of promotions now, but sbc packs are essentially worthless themselves. I've only got 1 sbc player in my squad as it is. As for packs, it's rare to get anything good out of them, especially any sort of tradeable reward which feel like they have a lower probability of a promo card in general.
Personally, I'm talking about implementing sbc's better as a whole. Make it so that even creating an infinite grind isn't necessary, and that way there is no headache with sbc bans or people using 3rd party software to complete them. It's the end of June and EA are still putting out 84 x7 or 85 x 5 combo upgrades, but they don't have enough big sbc's for people to dump their fodder into, which is also causing a complaint. At this time of year they need to be creating better packs, instead they are just copy and pasting their old content.
