Here's the rub.
Somewhere in FDEV there is an EDH actuarist that has a spreadsheet listing the minimum time required to obtain each and every G5 mat in game, even with the most optimized gameplay loops players have devised.
They have evaluated average player tolerances (to the minute) for engaging in the grind before they get up and walk away from the game.
You can talk about crystal forests and geologic sites and the Jameson Cobra and Dav's Hope and HGSS relogs but you are basically avoiding the elephant in the room.
The crafting is the fun part, and FDEV doesn't give a rat's donkey about fun, it's completely about minutes burned.
It's too bad that the bean counters haven't encouraged development of crafting mechanics rather than material gathering mechanics.
People would be all about testing and trying builds, buying ships (and skins), instead of unplaying the game to minimize the grind.
Oh well, 7 year old game on maintenance mode.
