You keep repeating your opinion like it's a fact. You don't like it, that's fine. Games are subjective. A lot of other people like me are finally enjoying exploration for the first time because of the FSS.
That's the subjective stuff^^^
If you wanna talk objectively, the FSS is:
1. faster
2. tells you just about everything in the system up front
3. cuts out unnecessary travel time for systems that you don't want to travel around in
4. reduces RNG by letting you pick your targets
5. makes more money
Sure. But those objective points you stated are subjectively positive. That's where im coming from because not all of them to me are subjective gains.
