It's was too SMG focused with the map design, but rifles are great for the War game type. Also, we haven't seen the size of the other maps.
Not sure about the divisions. Everyone used Airborne, Mountain, or Infantry. The Expeditionary and Armored divisions didn't offer enough to trade out one of the first three. They need to add a wildcard basic training where you can take one perk from one of the other divisions.
Example: Moutain Division has silent footsteps and ghost, but no access to suppressors. Let the Mountain Division users have a wildcard perk from one other Division. That can be the SMG suppressor from Airborne, the third primary weapon attachment from Infantry, or increased explosives resistance from Armored.
As it stands now, the Divisons are killing class variety with this limitations. There will be zero people playing Search or Hardcore not using Mountain.
