My personal opinion is:
The map is better than the basegame maps but
- to wide open space (except the tunnel areas) - there is to less cover between the flags (maybe they intorduced the smoke launcher for this problem)
- its hard to identify enemies in front of rock textures
- 128 players are to much. Just watch the map flow for some minutes. You will see most times ab bubble of 30-40 teammates running from flag to flag while the other sectors nearly has less than 10 players to capture
- Traveling between the bottom areas to the top areas needs to long. Thats the reason why most players stay on the top or middle level. The bottom level is to unsued because of leak of cover
