1.3 is in Experimental only, so casual players (huge majority) cannot test it, so you cannot see how they behave.

I'm having a hard time seeing how stopping people from spawning on points that are actively being captured transforms the game into a mindless FPS shooter. If anything repeatedly spawning on a contested point seems like a mindless activity🤷

Most pepople in this game don't follow the overall strategy of Conflict and like @Technicolourmatador already said it's usually a handful of people in any given server that are moving the game one way or another, it sounds like your complaint has more to do with that then any specific game mechanic. Why not wait until these changes hit stable servers to see how they affect the game instead of trying to predict how you are going to win every game?

We can take a heli with AIs and drop one AI in every enemy base, that may be captured and has no defenders. This way game becomes very static and mundane pseudo-strategy. Drôle de guerre in Reforger.
