Even with the 100% suring packs are probably going to change, cheating on PC will not. I'm sure EA have tried but clearly they are not keeping on top of it. The same cheaters on SB, Fut champs, draft, rivals have been there for years.
Got a ps4 for xmas, it came with fifa 20 but I sold it and I'm going to wait until fifa 21 to buy a ps4 copy.
I can name several different cheats and your telling me none can be stopped by a billion dollar company?
100% green timed shot, 99 rating+ all traits, 5* weak foot and skill moves, using trainers to just skip the game and give them the win, using legacy defending hack, auto buyers and there are no doubt more. More people would just hack good accounts on PC but because you dont even stop them they get the feel they can just "earn" it for themselves.
Sort it out!
