Wake Island is a really beautifull map, terrain change as bunker, building and vegetation are really nice.
I find it just little unbalanced in breakthrough, American have too many tanks and it's really difficult to win with japanese. This may have been due to too many support numbers due to the week end challenge.
That's a cool map but Iwo Jima is the best (in breaktrough).
For me pacific map are really top in breakthrough, i love conquest but for these 3 maps breakthrough is the most suitable. Even if Iwo jima is a good conquest map as the old BF.
