There's a need for massive change on pro clubs. From top to bottom.
The game play is so unbelievably sloppy, players not running to the ball, strange controlling habits at times and all sorts of other madness. It's difficult to play because of this.
Secondly, there should be a token system in place to allow clubs to purchase better Al players, maybe something along the lines of skill points in ULT Team, where you earn more tokens by playing better, bonuses for trophies won as well. Al players are currently shocking, half of them wouldn't get into my local team's reserves.
Another issue is that you cannot make substitutions. Why? I don't know. Why the game has gone on like this for so long I do not know, it's such a simple feature to add in.
Maybe it's down to the focus on having injuries for players when it doesn't do anything, I mean, you don't have to come off and they're not carried on from game to game, really pointless feature.
Tactics should be more in depth, like career mode where you can edit individuals' instructions. It's also farcical that you have 2 defenders back on attacking corners which leaves you vulnerable everytime you don't win the ball from a corner.
If it's down to the fact pro clubs makes no additional money maybe FIFA could introduce packs, for example a stadium pack you unlock for your club, token packs to give you funds for your team. To counteract anyone just purchasing a crazily good Al side, limit tokens to so many per club.
This game mode is my favourite but it could be so much better, it seems to be forgotten by the makers of the game and it's sad.
