FUT was the best and worse thing ever made for FIFA. It gets EA a shitload of money while leave us with very little innovation to the other modes. CM has been pretty much the same for more than a decade.
Although EA apparently won't be showing anything about Career Mode at E3, which gives us some hope since their biggest changes aren't announced til august or a little before. Last year even the developers realized not much was done regarding revamping CM, maybe this is the year.
WHat is good about FUT? Name me atleast 1 good thing about it, it is ruining the whole
normal gameplay of FIFA because you can dribble with 1 pumped player around the whole squad of ur opponent, you can score unbelievable 50m goals with scissors shot, you can run for 90 minutes without any affects of fatigue on your players, you can score with fucking RABONA from the free kick

etc. etc. The idea that any player could build his own squad and battle with it against others is ok, the idea that you can improve your squad with stupid +stamina, +skill etc. cards is horrible, oh and the fucking donate system that is giving you the opportunity to buy better players to get easy wins

instead, they should upgrade and improve the gameplay, remove glitches, improve FPS, improve the AI of the defenders and goalkeepers, create normal online lobbies for the people across the globe, give us the possibility to change fucking colors of the shorts, color of the radar, give us possibility to see the ping before we start the online match, give us possibility to change the outfit of the referee because 10000 times my team or my opponent's team had the same colors that the referees had, it's pretty simple and easy things to do, yet EA sports failed to fix it since forever, while in PES they have opportunity to change everything about colors/shorts/socks etc. atleast
