What if we stop talking about Nerfs and Gold Rushes , and start talking more about having all gameplay balanced. Surely that's the underlying problem and one that the player community should be most vocal about
Balanced to what, though?
An average player?
A skilled veteran?
The best player in the game?
A Cobra III?
A Krait?
A Cutter?
Credit earnings?
Material earnings? (in several different types)
Take credit earnings of exploration and trade - exploration it barely matters what ship you do it in, and the necessary equipment is generally pretty cheap (sure, A-rated fuel scoops are expensive, but C-rated will do if it's just credits you're after). Trade on the other hand the bigger the better - a T-9 can earn about 50x as much as a Sidewinder hauling exactly the same thing - more, when trade missions are considered.
So if exploration and trade are set to have the same theoretically maximum profit when done in a T-9, exploration pays out incredibly well for a Sidewinder. But if exploration and trade are set to have the same profit for a Sidewinder, then exploration pays terribly for any bigger ships.
This could be "fixed" by making it so that you couldn't make maximum exploration profits in a Sidewinder - you needed a fully-fitted large ship with a wide range of sensors which couldn't fit in a Sidewinder - 6A gravity analysers, 5A thermal imagers, 5A Very Extremely Super Detailed Surface Scanners, and so on.
That "fix" would be incredibly unpopular with explorers who generally don't care exactly how well their profession pays but do want to be able to take a ship they enjoy flying on their three-month voyages.
It is necessary that the supply / demand system works realistically. Prices should depend on the needs of the population, industry, and economy of each sector or system. The bad thing is that Fdev understands all this very well and can probably do it, but for some reason does not want to change it(((
The majority of the trade economy does work like that.
If people want to get involved in that sort of thing, they can grab a cargo ship and get hauling things like Coltan and Indium and Crop Harvesters. Lots of interesting supply and demand, price fluctuations dependent on player trade and local political factors (weapon prices rise a bit under pirate attack, for example).
There's - realistically - fairly thin margins for hauling most of this stuff. A typical trip in my Krait II (128t capacity) will make me about 150,000 credits profit. [1] And it'd make quite a bit less than that if lots of other people were doing it and meaning that supplies and demands were getting tighter.
There was once a time this process actually affected a significant number of players [2]. There were major complaints as a result. Frontier now understand very well that the majority of their players aren't interested in this sort of thing and so made Tritium immune to supply and demand.
[1] If I'm lucky it'll attract a pirate to kill, which is where the 'real money' is.
[2] Palladium has a very slow regeneration of NPC supply, so most Palladium-selling stations don't have much stock. For a while the game generated lots of "source Palladium" missions with very high payouts (500t for 40 million credits, or similar) - still does, from time to time, though not as large - and people took them. The combined effect of people taking them was that the Palladium supply ran low bubble-wide, making the missions difficult to complete (you could mine the Palladium, of course, but mining several hundred tonnes of Palladium isn't a quick process). So to make the money from the missions you needed either a secret Palladium source other people didn't know about - hard, with EDDB and the like, but not impossible - or to mine for the Palladium instead - or to spend hours hopping round a whole bunch of markets picking up 10t a time.
The player response to this was not "wow! this is an amazing supply and demand economy with dynamic gold rushes in response to player activity!" it was "Frontier are clearly incredibly incompetent to add missions to the game which require independent thinking and might sometimes not be possible, stop it now!" (only with more expletives)
The lesson was clearly learned.
