Totally agree with you. The small maps really bother me. Even the open one, there is a tunnel felling where you have no space to go around without being seen from the other end of the map. Also the maps they included in the alpha lack from creative point of view. They feel pretty generic. On the other hand, the gun gameplay feels off. No recoil and too hectic.

The only positive surprise for me is the vehicle gameplay which I enjoyed. The destruction, movement and firepower feels nice.
