The problem is that the economy isn't realistic, like at all. The prices are fixed for the most part, it doesn't generally respond to "events", even the BGS has a certain level of predictability to it. Fdev hadn't fixed the demand bug, or alot of bugs apparently, and basically engaged in price controls and market fixing/rigging. (That would be the real world description of what has happened.) The fact that Painite prices are falling when technically according to their own in game lore, prices should be sky rocketting right now due to the Federation and Empire placing buy orders on everything in preparation for war. It makes ZERO sense.
While your statement is technically correct, people have lost no actual credits in their accounts, they have lost value, specifically the value of their time. The reason I use that term is because Fdev has said it on multiple occasions "We value the players time." In other words Time is a commodity in this case just like any other, and what Fdev has done is essentially devalue the player's time by 60% or to put it another way, it now takes 60% MORE effort and time to earn the same amount of credits as they did last week. This is a pretty steep devaluing to do at once.
And I feel I should point out, this doesn't make combat players any LESS poor right now, this doesn't made traders any more efficient right now. All those other professions who's pay was a joke last week, is still a joke this week.
And since the PWA is still broken, one has to wonder how Fdev will get the data to show how core mining is balanced with respect to these new changes since no one can do core mining.
What I along with other people are wondering is why did they start with mining, why not the other professions that clearly needed a buff, that is completely obvious and irrefutable, yet they are speculating on mining. Even the announcement said they are "messing with the numbers over the next few weeks". Why? If Fdev knows how mining needs to be balanced why do they need to "Mess with the numbers", shouldn't they already know by now? Shoudn't they have already crunched these numbers and concluded, "Yep we need a 60% nerf", what is the need to "Mess with things". And more to the point, if they have to "mess with things" then perhaps they should have left it alone till they were more certain and perhaps, again, buffed the other professions with more solid numbers FIRST and THEN looked at mining.
Fdev speculating at their own game, is honestly painful to watch.
