Maybe this is more aligned with casual players? Yes there's a list ELW on the forums and such but what about the player that's not on the forums and can only play a few hours at a time and doesn't know everything there is to exploring I.e. the casual player. How long does it take to get to Elite with combat if you knew exactly what to do? All in all it should equal to the amount of time and effort according to the other classes, Combat, Trader, IMO.
I think it's much more likely that Frontier just doesn't think that much about exploration, and that it's a very low priority for them. Actions by the devs consistently suggest this, both from a development and a support point of view.
For example: comets are in the game. The Stellar Forge not only models their gravity but also places them in space procedurally, they have been there since before 1.0, they are just an unfinished mechanic without graphics. For over two and a half years they've just been on the sideline partially implemented, pushed aside for things like CQC, Power Play, Wings, Engineers, Multicrew, Fighters, etc.
Another example: they changed planet generation in 2.2 and reduced HMC and MR worlds into beige mundane planets with very low variety in both coloring and terrain. 2.2 went live and Frontier never even realized that it had happened. They now agree it needs fixing, but we won't see any changes for a long time yet, most likely sometime during season 3. They changed it without even considering the impact or consequences it would have on explorers and how we play the game, it just never occurred to them.
As for exploration changes in 2.3? I think we now know that most of the best changes are simply fixing things they broke before, and adding some scanner blueprints to the engineers that should really be quality of life improvements. Combat players get weapons with all manner of special effects and perks, explorers get QoL changes we need to grind for. No new mechanics, nothing that changes
how we explore, just QoL changes. But then it's really hard to add creative and game changing secondary effects for explorers when our game mechanics are so incredibly shallow, there just isn't much to work with. It's why Ram Tah simply flipped a switch and
BAM we now passively detect alien ruins while we fly about. How else were Frontier going to do that without actually developing some interactive mechanics for us? It was far easier to just passively flip a switch than actually put any dev time into exploration mechanics. That pretty much sums up how Frontier feels about exploration.
Honestly the fact that the new camera will be the most useful thing explorers get with 2.3 speaks volumes to how neglected we are by the developers. We get something to take better screenshots with while we sightsee and it's the best game changer we have gotten all season.
If it's not apparent, yeah I'm feeling a bit jaded lately about Elite Dangerous...
