I would rather have the reviewers test the game on live servers than have BS reviews... like by example Battlefield 4 and many many other MP focussed games.
Also, we had tons of people giving their opinion on the Alpha & Beta version (I.E. it's addictive and people love it).
Actually, reviews should always be done on a retail version of the game, preferably bought by the site that will have their staff review the game.
Everything else is previews, which is good enough to let the enthousiasts know if they want to take the risk to buy day one or order.
