But what would be wrong in saying: "ok, all the other mods are nice to have, I am happy if I find them, and not much worse if not. But I just need one specific mod at quality 6 or I will be miserable. I'll just get it from creative menue"?
Also, have you thought about simply increasing the player block damage in settings (I am assuming that exists, if not, ignore that point)
Higher quality mods drop left and right in the game, and the trader inventory exists for players who don't want to loot all that much. Throwing away the last vestige of true randomness in the game for just one single item you can't live without would be a fix with the sledgehammer.
You can still have RNG, though. If upgrades are based on crafting and require you to read multiple of the schematic to improve your skill at crafting so you can craft better quality levels, you still need to find those schematics. Some schematics are designed to drop constantly (vehicle headlights, though those of course don't have levels) and some schematics are designed to drop rarely (supercharger, which also doesn't have levels). They could easily do a pass over the schematics to adjust drop rates so that they drop at a random enough rate that you might not be able to craft Q6 in a given game without playing for a very long time, but where you could get lucky and be able to craft Q6 early in the game. That would give you the randomness while also giving some structure and keeping things more balanced. And it would make it so you're unlikely to craft a Q6 mod in the early game, while still having the possibility of being able to do so if RNG favors you. It would also mean that you have a path towards being able to craft a Q6 mod.
I'm fine with the idea of RNG dropping something nice early in the game, but not a Q6 of anything. That kind of RNG is bad for a game, imo. If you get lucky and get some really good Q6 drops in the early game, it pretty much makes continuing that game not really worth doing. There isn't much to work towards and there's little challenge if you were to have a Q6 weapon or something else that's going to push you far above everything around you. You see people regularly comment about how the game ends once you have all Q6 items. Why do people think that? They obviously can still go fight things and mine and build and whatever else. But when there's nothing else to find because you have the best stuff, it takes a lot of the fun out of the game. I've played games where you can find the "best" weapon in the game early in the game and then even though you find a lot of weapons throughout the game, you never change your weapon. It's boring. Now, I know not everyone cares about finding or crafting better stuff, but a lot of players do. And I would be willing to bet (this is just my own belief) that more than half of the players like to find and craft better stuff as they play through the game and generally stop playing the game once they can't improve anymore. At least on PC. Console players seem to have a different mindset, at least based on what I've seen posted, and they tend to play the same game for hundreds of days. I don't know if it's just that they are new to this game style that promotes playing many games rather than a single, long game, but they do seem to treat it differently from PC. Or maybe that's just the few posts I see and most don't do that. I'm not really sure. Either way, a lot of players want to find and craft better stuff as they progress. Letting the best stuff be available on day 1 through uncontrolled RNG just isn't a good thing.
As a final comment, which I've mentioned before, you are basing your statements ("Higher quality mods drop left and right in the game") on only your experience in one (?) or even a few games and being lucky with RNG. If you were to play the game and get the supercharger schematic dropping in the early game, you might be of the opinion that it is an easy drop to get even though it is probably the most rare schematic to find. I can tell you that in my game, I have a full weapon mods box, plus about a third full tool mods box (armor doesn't matter since there aren't levels on anything but temp mods and I've only seen one of those drop). And I've sold a lot of mods that we didn't need, but only Q1-3. In there, the majority of the mods are Q1-2. And that is with having sold a lot of Q1-3 mods but no mods over Q3. Even considering that I'm using some of the higher quality mods, the ratio of drops even at high level (I'm basically end-game right now) is probably around 50% Q1, 20% Q2, 15% Q3, and the rest split between Q4-6. At end game, that's pretty sad. At the very least, the Q1-3 should drop off by end game so you aren't finding them, just like you're not finding primitive weapons at end game.
