On player career mode - my issues that could use fixing.
1 - Striker stockpiling -on my Everton saga, as our starting striker, the team busted the budget on successive windows for more strikers. 12m on a player, Waris, who never started over Vellios, followed by another 15m striker the start of the next season. Had me, Mitroglou, Waris, Vellios, Kone, McAleny, Hope... but a decimated midfield and backline which saw my best players (Stones, Baines) transfer listed.
2 - Playing. 1860 Munich, started 3 careers. Kept getting the "you're in next match" emails from the manager. Never played. Simmed through two seasons. Even after a loan spell at Charlton and starting for the USMNT at the World Cup, the entire second season still never saw me play. WTF?
3 - Transfers - would be great if more variety showed up. As a mid-70s CAM (not) playing for 1860, would have been nice to see something other than Man u/City/Chelski/Barca/RMadred/Juve. Simulating six different windows at the same spot, Lazio and Spurs were the "smallest" offers I got.
COmpare this to Manager Mode, where Lukaku was valued at 45m for me, and I was receiving offers from all over. Soton? Sunderland? On top of the big squads.
Not everyone wants to play for a Goliath, some of us would rather slay Goliaths.
