Was a time when exploring required moving. Now you can explore a whole system of 1MLs without even moving.[haha]
Next patch: "Explore" the whole MW without undocking from SD !! [yesnod]
The current system is definitely 'not' exploring in my opinion.
You jump in, honk and move on, unless you want to tag a body, in which case you just point your ship at it and fly close enough to DSS.
Currently 'exploring' is jump to system no-one knows anything about press a magic button and know everything.
At least the new system requires some (not a lot) of extra work and you still have option of flying around the system to map planets.
BTW, you can continue to play exactly the same way within the bubble, nothing has really changed everything appears the same way as it did.
It only really changes when you go out further to completely undiscovered space.
Just my own opinion, I am really enjoying the new changes.
