Hi, i think these suggesions are helpful & good.

1: For inviting players, make a option where it can select all players from the lobby & invite them all.

2: Reduce the respawn time.

3: Sniper maps
(Desert, jungle)

4: sniper only game mode, pistol only (i think they only have point man only mode & knifing mode, but i can be wrong)

5: kick players from in-game
