You are usually a very reasonable person.
I don't understand how you can NOT see that too fast a progression through the game is a bad thing.
No-one's asking for a 10-hour unlock for everything, nor 20 nor 30, nor 40 or 50.
There's a post right here on the front page from a lady who endured 6 hours searching for some engineering materials, and not a single one dropped. That's not even RNG. That's just plain broken.
It's things like that that need to be balanced.
The way the Navy ranks unlock now is a good indicator of how things should be. They progress nicely while you just meander about doing your usual business. If you focus on them you can have it done within a weekend easily. That's fine.
Having to wait 3 years (as someone in another thread said, 2-3 years is 'reasonable') before you unlock the Cutter is just mind-boggling.
If someone wants a Cutter, and they want to put the effort in to get one, let them have a Cutter, whether they're green and will instantly drift it sideways into the next station they jump to (they'll learn from that) or if they're a multi-billionaire who wants to make a multicrew-enabled SLF-wielding fuel rat ship because why the hell not.
