Retire manta from map rotation

[Ikea]

Another issue with manta i dont see brought up much, no good chokepoints for interacting with people. If you wish to go across the map, you can go between the bar, between sec and the bar, and through escape. 3 main different ways of traversing the map. The issue this runs into is this much ways to traverse leads to hallways feeling sparse, each good map tends to have a few areas to congregate people around, see public market on cog1, or medbay on oshan. Manta doesnt really have any area like that.
