Yes, I really wonder about the daily offers thing. We know that the development effort is profit driven (only makes sense), so I figure there must be people buying them, or they would change it. I’m just happy they introduced a wider variety of items for purchase at lower cost and increasing frequency. I’ve bought a lot of imperial deeds from the merchant. Even if daily offers were “fixed” (including Arena), It would have taken me forever and cost more gems. So once they introduced the merchant, I stopped caring 
As far as other stuff that needs fixing - whatever it is usually falls into the “inconvenient but doesn’t affect my play much” for me - like the new troop display not working or similar. I’m not guild wars obsessed, so I don’t know the issues there. My requests for existing game are more enhancements that would make things easier but not stuff that is actually broken.
I do wish they would slow down the troop and weapon proliferation. I wish it was easier to get weapons outside the kingdom week - I had to wait forever to get Rope Dart and Duskbringer - well over a year. Other things like that.
My spend pattern sounds a lot like yours
