I bought the game about 1 month ago and I've been playing online, most of the time. So far, my impressions of this game:
-It's too fast. I play online and I just realised me and my opponents play using R2 button pressed ALL THE TIME. It's all about speed, again. I feel like I'm playing PES2007, again. Speed is too effective, and we can use any fast player to do anything we want (attack, defend, tackle, dribble...). It's just a frantic match of players running around all the time.
-It's still kinda easy too score from outside the box. Shoots almost always go to the goal (if you watch a full match in real life you'll see how many shoots just go too high or too far away, specially when the player is running).
-Pressing L2 to protect the ball is USELESS. The player just stops and watch the opponent take the ball away.
-It's not a football simulator, anymore. You don't have tactics, anymore. You just RUN. The faster your player run, the better.
-You don't have to tackle, anymore. Just outrun your opponent and you'll have the ball back. It doesn't matter if your marking with your striker and his marking attributes are low. If he's fast, you'll outrun your opponent and have the ball back.
-Auto-tackle needs to be nerfed. Most people can't hit the button properly, but AI will do the job. Again, you just have to outrun your opponent. No tackling skills needed.
-Why don't we have the option to mix kits, yet?! It' so simple! I'd like to play Milan using black socks with home kit, or Chelsea playing all in blue, Atletico using red shorts and socks... It's more important than having old stupid kits available (really, who wants to play with an stupid generic old kit?!).
They do that on Madden! You can fully customise the kit you'll play before the matches! It's already being used by EA, just bring something like that to FIFA.
-Why we still don't have numbers and actual position on our tactical table?? If you put a ST as CB it still shows him as a ST! So simple to correct... Or, at least, they could change the letter's color to indicate a player playing out of position.
-The movements looks unatural. Feels like Frostbite engine was a downgrade...
-CPU still reads minds and never misses a pass or first touch control, like in all EA games (Madden is exactly like this, too...).
-GK seems a little more natural than before. I'm not sure if they're still supermans when face 1-1, but they seem less dumb from long shots.
-Why the hell do they still have the white line around all the dots in the radar?! Come on! It's more confusing than helpful!
-The negotiation animations are a nice add, but it limits you too much. You can't offer more than 1 player as payment (and can't even offer a player + money right from the beggining, they have to ask for it). And the "tense" backing track all the time is a bit of annoying.
PS: The songs are pretty bad, too... But that's maybe a matter of taste.
