The other elephant in the room is that everyone trading is in their own little world. If you've got 10 traders in a system all in solo or groups then you suddenly see a market dry out and not know why. We don't even know if the traffic reports are actually accurate and working since a lot of other basic stuff in the game is bugged there's currently no way for the player base to test this. If everyone was in open and you saw someone on your trade route, the sensible thing would be to swap to a combat ship and run that trader out of dodge. Oh look, emergent gameplay
Most of the traders complaining about this change have created this situation themselves by hiding in open and using crowdsourced tools (which I personally see as the equivalent to an aim bot for the economy). You can complain about lack of ingame tools (which I agree are needed) but you can't really complain when FD make fixes to the economy. By comparison trading is the easiest, lowest risk thing to do in the game and traders have had it too easy from the start.
Anyone saying "be thankful for the 84's who backed" Yeah people are thankful, I'm an old frontier player myself but you gave funds for them to make the game their way you have no entitlement to cry when they do. Saying you're going to ask for a refund because they changed the python is quite frankly pretty damn sad. If you were all in open the way fd intended the game to be played then maybe you'd have the right to complain that your play style was nerfed but you've nerfed the rest of the food chain yourself by grinding up in solo then moving to open with your anacondas. If you're complaining that the game is getting boring it's coz the majority of the players are grinding in solo, ofc it's getting boring.
Before anyone brings up the offline debate then yes it sucks that there's no offline but if you're still playing then you've accepted that you're part of a changing galaxy, economy included.
