It is a legit review, and it happens all the time in the industry. I know oohboy is anti-EA (to the point he is rooting for hundreds of people to lose their jobs), but to go so far as to essentially claim none of the good reviews count? I guess he thinks that if somebody dares like a game that he doesn't, it doesnt count.
The only way they are legit is if the reviewer reveals that they reviewed the game in an EA controlled environment and didn't actually play it online how everyone else would have to play it. Even then, those reviews become irrelevant.
When the final release product reviews are so much worse than the beta closed environment reviews, you have to question their validity. Eurogamer Sweden gave the game a 100 perfect score. Eurogamer proper and the German branch gave it a 40. One played it in an EA controlled environment. Two played it after the game was released the same as everyone else who bought the game.
Polygon is a good example of what has gone wrong with the game. Polygon gave it a 9.5 originally (they played 50 hours or so and had a blast...on the beta version). The day after publication, they dropped the score 8 based on the server issues. Then, four days later, they dropped it to a 4 because the game had changed in a lot of ways that made it less fun.
EA has changed the game, which IMO makes the reviews of the beta version be irrelevant for the game in its current state.
