I see what you are saying---thanks. So, new spawn point generation and spawn "right click' option in a zone are out. BUT there is no apparent reason why some of the other ideas might not be part of a possible solution.
(1) Spawn point unknown to enemies not cheating.
(2) Several FIXED points (say 2 or 3) and one spawns randomly between them at fixed intervals.
(3) that spawn points could be "hardened" with AT guns, "hull down revetments," spotter positions, minefield, or friendly artillery coverage, etc..
