I think BF3 premium was brilliant. All the maps had a clear theme, and the new vehicles were great fun. Aftermath and Endgame jeeps? Those things absolutely destroyed if you used them right. Especially endgame, with the 4-round rockets that could kill a tank in a volley and the aa missiles.
For me, second assault should have been Damavand just for the rush, Noshahr for the meat grinder noob fest that is TDM, and then two conquest maps. Sharqi peninsula was good for rush as well, that could have been in. Maybe even some Endgame or Aftermath maps.
