Since starting this thread, I've done some serious soul-searching, and I am also going to wind down and quit FoE. I went to the discord today after vowing many times I would never install that piece of *expletive* and discovered I was right. I'm deleting it from my computer, and that was the final straw -- since INNO is determined to destroy this game for me, I see no reason to continue to support them, either by money, recommendation, or by my continued participation in a game that no longer holds any fun at all for me.
I did notice that there is a much bigger thread on discord about how FoE has been destroyed for many, many people, for pretty much the same reasons as have been listed here, and many people there saying they are quitting FoE. It's such a shame because it was really fun for a while, but I'm not the type to throw bad money after good, so I'll use up the diamonds I still have and then delete my cities and say goodbye.
