OK, so it is impossible to change the spawns from random to a cycle, but I have found a better solution!
I can change the spawns to limit the spawn options of the other team where there would be a spawn rape scenario.
In other words, if a team spawns at Assault/Defense North (the raped spawn) the other team would NOT be allow to spawn at Assault/Defense South (the cheap spawn that does the raping) and would instead spawn at another location. Would this be desirable to everyone? This would keep the random spawns but get rid of the stupid spawn raping scenario that occurs.
