When it comes to mapping systems, there seems to be 2 main groups. Them that feel they must scan all, and them that scan what interest them (me)
There was (and i guess still is, as you can map...) a nice thing some explores did, in places of interest. They would scan one planet and maybe another if it was really interesting, leaving the rest open for anyone else that happened that way... i love that, some system with 7/8 different commander names, like a log of visitor.
Now this was a while back, over a year (as i took a years brake waiting for beyond to finish), on a live stream, devs seem to like the idea of scanning a whole system to them selves, i pointed out that i thought that was annoying... Going out to a system and seeing one name splashed over every little rock.
Here is why this is important. We now we a bonuses for fully mapped system. This had been brought up before and seems as many liked the idea as didn't. And it was pointed out that such a bonuses should not be applied as it was unbalanced, giving a bonus to OCD players that had to scan a full system else they felt worried. But here we are, bonuses, as if the devs in charge put their idea of what's cool into play (and that's fair, its their game, but at the expense of others)
The telescope scanning is aimed at the people that want to scan a full system. Making it more interesting for them. before, they had to fly to each planet to scan... wow that must have been horrible. But this update was not an improvement for the explorers that like to only visit thing that interested them. the explorers exploring cool things and not just cataloguing the galaxy.
So if there are people upset with the new system, rightly so. yes it has come cool features, but has made exploring for explorations sake (looking for cool stuff) a little less fun (My opinion).
Would only be fair to see some adjustments to the system. not take away what is there (though that has been done in this update) But offer some balancing to exploration types. Allowing for the fly by explorer that likes to have a look at a system map, while still travelling at speed.. instead of having to park up and scan everything to look for that interesting rock.
and if i had my way... removed the bonuses for full scans. that's pandering to people that feel the need to scan a full system, and encouraging that sort of game play over the visitor tag style of commanders vising a location.
(imagine if there was a counter version to full scan... if you only scan the star, each time data is handed in for that system and someone gets a new discoveries (Planets you left) you get a bonus.. silliness i know

but would offer a reason to leave a system partly scanned... intensives, don't do it )
