Its certainly more depth than the old system. Its not a removal, its a replacement. Technically speaking, an upgrade, an improvement... if you think it is an improvement. As i said earlier, i'm 50/50 on whether its better or worse than the old system.
If you replace something, you have to remove the other thing. If they had simply added the feature, I would still be playing Elite now. And it would have made sense to add the feature without removing the ADS.
1. The ADS would tell you information about the system. Based on that information, you could decide whether to investigate the system further.
2. If you decide to investigate further, you fire up the FSS and get more information on the planets in that system. Based upon that information you could decide whether to investigate planets further.
3. If you do decide to investigate further, you can go to the planets you're interested in and probe them or land on them,
The thing that kills exploration for me right now is that I am forced to play the mini game about every single system I go through. If I could have used the FSS only when I needed to (I find a system that could be interesting) it's frequency would go down a lot, and the grind aspect of it would go down a lot. When I first learned about the FSS I was positive about it. The mini game itself isn't the issue. The frequency is.
It's not better or worse than the old system. It's on par. The old system was lacking in depth. The new system is lacking in depth. You master the FSS in an hour or so and after that it just is busy work.
The duality I have about Frontier in this is, that I do believe there are developers who do care about the exploration mechanics. That's why I am very careful to direct my ire at Frontier, not the developers. I do believe the marketing aspect is the reason exploration gets as little priority as it does. A well thought out exploration system doesn't sell and doesn't make jazzy marketing. Pew pew pew and explosions do.
