Konami have no idea that people want a global edit function, or that people want to edit the gameplay themselves (only kits etc.) - the vast, vast majority of people who buy a game put the disc in the drive and play it as-is with no thought of modification. Like it, or don't. Play it, or return it. We're a mouthy minority, here. The 1%.
It's like the guys who say "play manual to make the game great". I can barely get a game on the Xbox One with a below-average MyClub team, let alone play a manual game, and I wouldn't want to anyway - I don't want to turn a Premier League team into a bunch of Sunday League players and neither do the vast majority. If the default settings aren't fun, it's a bit of an excuse IMO (and it is just my opinion) to say to others "you're not playing it to its full potential". It works for you, it doesn't work for others. It's the principle. I want the game to be fun with the default settings, and given that they're exactly that - the default settings - it damn well should be. It's how the game is made, and set-up, to be played.
It's a football game, not a flight simulator. If full manual is the only way to play, where does it end? Left stick for left leg, right stick for right leg? Push back and forth alternately to walk/run? Hold L1 to take a deep breath and regain energy? Controller angle determines foot angle? (Actually, I like that one...)
(Also, if we're going to go down the "I paid £40 to have to do this" route, I think the bigger scandal is paying for a game that has 2016 on the box but features 14/15 rosters, as that's something that affects everybody, and not just the guys who read on a forum somewhere that editing every player's stats makes the game better, and then even CONSIDER it, but... We've discussed this.)
