Gameplay/Momentum doesnt feel real

So I've been playing this game awhile, and what I really don't like is how at least in online head to head mode you can have a huge lead and the other team always comes back no matter what defence you play. Its like its automatic, there's no real momentum swing that makes it really tough for an opppnent to come back. I don't know how many big leads i had, and it comes crumbling down and basically with the same play calls he uses. I don't think i'll be buying next years game, this one is based too much on "fairmess" (that is ai help) and not as much on what the online player does himself with playcalls, coverage etc... I think its broken.
