Regarding World Class difficulty (83+ rated squads) and any rating for Legendary, the AI is just completely overpowering in this version.
In past versions, once you faked or got away with one player, you always had space and time to make a move or get downfield.
In this version, if you fake out a player (which is very hard to do), or win the ball back or get around them, they have 1 or 2 other players that track you down right away, constantly winning the ball back. Also, if you manage to get by an AI player along the sidelines, their other defender (usually on of the CBs) ALWAYS catches up to you with speed and precision on perfect angling. They are just ALWAYS faster (no matter what player they are or what player you are) and the AI always makes the tackle (which has always been the case as well in past versions) when defending in their third of the pitch and you dribble anywhere near them.
In one match (my squad is 86 rated and their squad was all Bronze players with 61 rating and 0 chemistry), I was winning 4-0 at the half. In the second half, they completely controlled the ball the entire half and scored 2 goals. I could not manage to win the ball and when I did, they would go at you immediately and win it back. Total BS. EA totally upped the sliders and the team was completely different than the first half team. This version is just frustrating.
