All these changes seem to be interesting. Firstly, because you seem to be working on something new (especially for the economy module) which means that you more or less "care".
Secondly, because this seems to be a whole new big series of changes in the game.
However, I have some concerns:
a) Since you are pre-announcing all these changes and give a time-window of 2months till their deployment, I would suggest (and expect) that you will SERIOUSLY consider the feedback that you get from here (and elsewhere). That means that on one hand you should provide answers to the concerns raised by players. On the other hand, you might actually do some "tweaks" in your proposals instead of blindly enforcing them.
It would be nice to provide some additional details on the changes that you propose before actually deploying them. Therefore, players can give you more detailed feedback and you will be able to make adjustments before actually deploying the changes.
c) Since, you are going to do some "radical" changes I would also suggest to give some trial period, and make additional adjustments based on this feedback.
d) It would be nice, to present to players a nice plan and timeline of your ideas. For instance, you may say (as you did) that in the following 2 months these will happen. But for instance, you can say that you will provide 1-2 weeks to collect initial feedback (before deployment) and a couple of weeks doing the final adjustments (based on feedback) and then actually deploy. Then you could also say that after the deployment a trial period of e.g. 1 month would be applied where you will collect feddback and also evaluate your new changes. After this a new series of improvements could be announced, discussed and then enforced.
I know that, this model would take more time. Moreover, I know that this kind of feedback will interfere with your internal design and development model. However, I think that it is time to have a more open debate on the game mechanics and changes in order to improve the overall experience. At the end of the day, the design choices are yours, what I am asking for is some "time" and "space" for feedback from players. I bet that there will be at least a small set of comments/ideas/adjustments (out of the huge pile of comments) that you would agree with and that you have not foreseen in your plans. However, I believe that this is critical since the whole game experience is actually getting worse over time. Thus, improvements (player-friendly) should be done.
