I've not played this for quite a while but came back to it tonight, and decided to give all full manual controls a go. It somehow feels a lot easier than the last time I tried all manual in previous FIFA games, perhaps it's a little more automated this year. Either way, I wasn't very good but I loved it. Some odd stuff was pointed out to me, such as when your keeper kicks the ball from his hands on semi or assisted, it kind of 'locks' on to another player meaning you can't get a huge goal kick down the pitch. On manual, I was able to use huge, quick kicks to my advantage and perform a quick counter. I didn't manage to score off them but came close on a couple of occasions. The ball physics certainly feel more organic on manual, as shown when I used Hart to punt the ball quickly at maximum power, and used Rooney's strength to chase down the loose ball and muscle his way in on goal.
I'm seriously considering persevering with manual and learning how to use it. Just one question though, how much influence would anyone say that full manual has on stats regarding a player's ability to pass, shoot etc? I must admit I didn't notice a great deal of difference whether it was Wilshere or John Terry when passing. This would really influence whether I use it for a CM, as I don't want to have passing stats ignored. It would negate the need to sign playmakers and other such players in a career mode.
