Groupfighting's spawns are made so that the teams don't line up directly against each other, instead the left side of the spawns is in line with the enemies spawn, but the rest isn't, drawing cos im autist england
part of the issue with the spawning mechanic in the game is that everyone spawns at that point and to the side of it.(and possible rear) when the first row is done, it goes behind the the first row and makes another row to the side.
of course, you have to accommodate that when you make a map, so people don't spawn behind buildings, fences, map edge etc.
you can try and line up the spawns so that they line up right, but that isn't always easy depending on the map.
i like spawning in 50-100 bots per team when i make maps to see where the game is spawning people, and move the spawns accordingly.
