Be specific. What thing did I say that was incorrect. Those are the required steps.
Your opening statement was "If you want a greater FSD range (which he mentions) you have to do several specific things.", which is complete hokey. That's what you have to do to get a level 5 FSD upgrade from a specific source.
The complaint is, to get it, you have to play the game differently than you want to. If you wanted to be a (space) miner: there's no way work your way to that FSD modification without being an explorer, and trader, and wake scanner, and SRV pilot. Worse: It's not like there's only the "Go fetch 50 of these" (though those kinds of things do happen); but more "do this over and over until you get lucky".
Lol. Being forced to carry a wave scanner and being forced to spend five minutes pointing at things that leave the station. Oh the humanity! Additionally, most of the mats can - as you well know - be obtained via missions. If I was being bloody minded as a miner, refusing to do absolutely anything else, I could do it only via mining mission rewards. You're both factually incorrect in your initial comment about what 'has' to be done for an FSD upgrade and that FD 'force' our miner to do terrible not-mining things.
There are two engineers with G5 frameshift drives.
Who said anything about G5? Nobody except you.
You have to explore until you are a scout.
Travel 300 ly from starting system.
Or just fly about mining, because your guy in the example will cry if made to do anything but mine. Eventually they'll hit scout and eventually they will mine somewhere a long way away.
You have to find meta-alloys (try doing that without consulting the internet) which will include long-distance travelling, landing, "mining" in your SRV (unless MAs are still bugged and sold at that one station).
Or ask someone on a friend list to sort you out a hunk, in exchange for a bunch of stuff you mined.
Retrieve Sontil relics.
Oh, the pain! flying for an hour! Boo-hoo. Alternatively, the player swaps 100 tons of something he mined for it with another player. No rare trading then required. Mining FTW.
Now you have to level [the engineer]. I'll ignore the requirements on that because they vary: but assume you will have to drive along on planets for mats and do missions as well.
Let's not assume that, because nobody said it was G5. You were giving an example of what you 'have' to do to get 'a' FSD modification. So none of that levelling needs to happen. But if it did, then there is still no need to drive the SRV or do non-mining missions. Heck, we could just trade in a bunch of exploration data, accumulated over all that time we spent mining.
You are ready for your FSD mkV. Well, you need uber-rare arsnic (more planet mining), Datamined wake exception (so you will need to equip a wake scanner, possibly for a long time, and fly around scanning those), Chem manipulators (you'll have to blow up cargo ships or hunt surfaces a long time).
Or mining missions. Our example is going to cry if he has to play any other aspect of the game apart from mining, remember? They absolutely refuse to play any other part of the game, because you wanted your example to be as convoluted as possible. So they are going to do mining missions, where they can get everything.
If you just wanted a career as a miner (in a ship): too bad. You'll need to do all the things above.. a lot.. or you can't get your jump drive engineer mod.
Yes you can. As above.
