Your definition of exploring is NOT the same as deep space explorationI did.
And I have fun exploring.
You don't have to fly xx.xxx ly away to make new discoveries.
I have refilled my FC with Tri yesterday, and today I started to scan new systems already after 2nd jump.
And I have found system full of biological signals, not known in any online database.
Only 1090 ly from Sol!
It also has three red dwarves with huge rings that are de facto 5.,6.7. planet and several ringed gas giants.
It will take some time before I check all landables with biological, my FC has jumped several jumps ahead in the meantime.
I realized that keeping it in the front is a better way in case I will have some streak of non-interesting systems I can always "catch up" in my Phantom.
In short - FCs are fun, but you have to use them according to their in-game performance/capabilities.
DEMANDING to change it to your liking or considering them "generally useless" because they are not optimized for your specific idea of how to use them is IMO childish.
