I do agree with a lot of your sentiments - I spend about $1500~ per month.
I'll also say, however, that most of the stuff in the video shouldn't be a surprise. Honestly - they had mapped out everything about how the changes to Sage world would work - that should make it clear that it was the intention of the devs to roll it out. They wouldnt have put much thought into a preliminary vote that they honestly figured could have gone either way - they also said (when the vote lost) that they will 'delay' the changes. No one should have been surprised by this.
All that I really hope the dev's learn from this is - listen to your players, make the game fun. Don't try to cram events down everyone's throats and don't give away exclusive * because you're desperate for more money (thats a jab to your high spenders). If you focus on making the game fun and enjoyable from the ground up, you'll be successful - if you focus on making money first, you'll fail. It's simple - this is a game, people play it to enjoy it - you have to focus on why we play, not what you hope to gain from us playing for the game to succeed.
