The only thing that is required to ensure spawning on the map is an available (e.g., team compatible or neutral), unobstructed respawn point. Even if it is at the vortex of every dead player just moments before, has everyone pointing their LOS at it, and has the most negative weight you can imagine, if it is the only available, then it will be used. The two things that would concern me are the number of players v the number of respawn points, and what would happen if all the players were spawning, or they spawned and did not move off the points? And can the scenery obstruct the respawn points? I don't know how many respawn points are on this map, haven't looked at it. I don't know if the scenery can be moved to obstruct respawn points or not. But for a map like this I would line the floor with respawn points everywhere and surround the entire ship with a Safe Boundary so that if anyone for any reason spawned outside they would instantly die. It looks like an interesting map.. for about 10 seconds.. but then it may be like baseball - it may be more interesting to play than to spectate.
