These changes are not very good, or even well thought out. In economics, this is a regressive "upside down" approach. The amount of money put into the system is by players that don't have billions in credits and may have a few thousand, these "changes" will not do anything much except make it hard for new players to existing in the game. If rewards are lowered, but the costs are raised that, to me at least seems like it would make things worse. It will cause new players to pool around on starter worlds grinding for credits just to afford the travel costs locally, making repairs to gear, and ultimately leaving the planet to find better gear at Fleet or on Capital planets and major hubs.
This new system will only increase inequality as players already in-game for a while will have amassed a "fortune" to afford the cheaper but exotic gear and greatly outclass others trying to just play the game but are met with financial obstacles and credit sinks that won't be much of an issue for someone with 1 billion credits per Character and 4 billion in a Legacy bank and same in a guild bank. It will be just unfair.
Think of this new initiative as a sales and consumption tax: Spend $50 on clothes for your kid, and you’ll pay the same sales tax as anyone else in your area, regardless of income. The poorer you are, the greater the share of your resources the sales tax gobbles up.
While I can see the lowered income and other secondary changes. Making essential services more expensive while reducing ways to earn sufficient credit is not the way this should have gone.
