This was a good decision, but really it only hurt the casual/afk type player. The credit/per hour likely hasn't changed, and in some cases it could be higher.
Rares are a virtual guaranteed $15k profit per ton. You don't have to worry about someone flooding the market, ever.
Here, to stop people from complaining, I'll just give them what they want:
1. Outfit the ship with the best LY jump range while carrying ~10t of cargo. Even a Hauler with a good FDS can have a high jump range. You don't need that Asp for this purpose.
2. Go to nearest rare station, buy the stock (~10t)
3. Fly to the next ~150LY rare commodity station
4. Sell your cargo hold, buy the available rares & repeat.
It takes ~45 seconds to perform a system jump. This include 10 second cool down, 15 second recharge, then the actual travel.
Even if you have 15 jumps, this equates to 11 minutes of your precious, but non-resuppliable life.
Add in a few minutes for refueling (if necessary). This will vary on your fuel scoop & fuel tank.
Add a couple of minutes for travel to your next station. This will vary on distance from the sun.
So in well under a 1/2 hour you can still get nearly 150k credits or more in one run.
This isn't as easy as waiting for the 15 minute timer on the commodities, in which you can surf the internet, watch TV, love your wife, etc...however the end result is that the credit per hour is similar.
After reading about rare goods changes and some of the comments I decided to register just to write this simple post of appreciation.
I am mostly trading in game right now and I have quickly realized how broken rare goods economy was. To the point I considered it to be a bug. Newest change is definitely a good one. rare goods are a good income source for exploring players and not attractive to hardcore traders.
So again thank you for this change and do let some of the posters to discourage you. This was a good decision.
