A few examples:
When you cut off a passing lane and your player opens his legs to let the ball go right through
Your opponent passes the ball right to your defender and he flails his leg out having the ball deflect off him straight to another attacker
You pass to your player and they randomly stretch their leg out deading any momentum you had going forward
Your opponent passes the ball straight to your defender and sprints up with the guy he was trying to pass to and auto-tackles the ball right off perfectly (yet making a tackle with a defender makes the ball bounce away rather than sticking to his foot like every striker in the game can do)
I won't act like I've lost a game solely to these animations, but they certainly factor in for me and my opponent. I just want this game to be better and they've introduced some really good things this year but the countless gameplay issues have severely detracted from that. FIFA will never be a true eSport until they fix these, and many more, glaring issues and finally open up to the community about how this game works.
