Ok, let´s get some things wright. Nowadays, games are not programmed for consistency, it´s the other way around, and frankly, I like that.
Then to all those seeing all the mistakes in the game, first of all, you have to undertand it. It´s not matter of well you play it, instead it´s a matter of reading the match, and understand why the game does certain things to you. Most of the guys here don´t realise that the matches flow based on momentum. I have seen my team play like garbage, and that´s where I know I have to calm down, pass the ball around my defence, slowly building momentum.
When I have the momentum on my side (it´s really noticeable), I can see my team winning lots of 50/50 balls, players winning speed (even the slower ones) and passes going better. That´s when I start to attack and risk a bit more.
If you understand this basic concept, you´ll enjoy this much better, and accept the fact that sometimes you have to loose situations where you think you should always win. Most of the times momentum is interpreted as scripting, but really, it´s how you actually see things. Be aware of this, and play according... trust me, it´s a much better game when do it.
