That's an easy answer. They will listen 100% the people that spent 850 million dollars on Fifa 19 buying FUT packs alone. While lootboxes are their main goal in EA games we (offline players) won't have voice anymore.
They probably will release the game with some "new" gameplay features and after two months of damn FUT players complains and "feedbacks" the game will go back to be the same end-to-end-pinball-like bull**** like every year.
EA is winning so much money with FUT that they could easily create two versions of the game, one for online players and one for offline, but why would they care to do that since people will continue buying it blindly anyway, right?
