Fifa 18 career mode's latest upgrade with the transfer system was a good change that was needed, it added something new to the game, however the repetitive nature of career mode is still the same. After 2-3 seasons it just seems the same old. Personally i would like to see a few small changes added to this years game that give you a reason to play more seasons before it gets repetitive.
1.Carry all player/manager stats over season by season, e.g. goals, games played, trophies won. For instance it would be great to hear the commentry team mention that the manager is about to manage his 100th game for his current club, or that "lacazette" has just scored his 100th goal for arsenal. You could even add personal records like Premier league all time top 10 goalscoring list. You could challenge youself to get your newly promoted youth academy striker to over take Alan Shearers Premier league goal scoring record, (this could potentially take anything up to 10 season).
2.Players having their own personalities and you have to manage them accordinally to get the best out of them through out each season. i.e. Mesut Ozil - less defensive duties or he will request to play for a more attacking team. Playing a striker that likes to get in behind as a target man asks you to change tactics or he will demand a transfer.
3.Actual teams getting bought out by a "billionaire" and challenging for top trophies, buying top players. (this could be your own club or others).
No1 is a main priority that i hope you would look to get added, none of these requests are game changing but would definately make career mode more interesting and hopefully get rid of that repetitive nature.
Please feel free to add any pro's or con's, and you are more than welcome to add any of your own ideas.
