I think this DLC is a new breath for BF3. Basic maps (caspian border and firestorm operation apart) are too small for 64 players and some of these maps remind me a row of corridors .
These DLC maps are really adapted to BF3, it's mean adapted to a game where teams have to play strategy.
I like Strike at Karkand with the new engine. More positions to hide (apartements, stores), more destructible environments. This map is a perfect mix between close combat and long range fighting.
Not so much véhicles. I like this map in 32 players Rush Mod
Gulf of Oman is nice too. Large beach for best tanks confrontations, convenient for swoops with jets or choppers. After the city for close combat, high buildings for the snipers. It's easy to play all the class of the game.
These two maps are perfectly balanced and allow various approaches of the fight. Gulf of Oman is the map you have to play to 64 players in conquest.
Sharqi Peninsula is probably the smallest of all, but we do not feel cramped as on Grand Bazaar. The TV station is a great place for snipers. I like to play this map in conquest.
Wake Island is not my favorite map, but it is very stylish. The atmosphere of colors is magnificent. In rush mod it's I think a very interesting map to play.
