Other people have, indeed, expressed the same thoughts regarding unsegmented events as yourself ..... but it's good to add your voice to the general idea. Although this is the players forum, I like to think that Pixel read it occasionally for feedback 🤔.
New events all seem to follow a set pattern now .... large events have similar energy costs over 8 levels/ 3 challenge levels of predictably fixed values/ achievements give the same reward for each level/ similar values (slightly increasing with each new event...) for equipment. It's like they've refined a fixed template for the structure & reward parts of new events & they're sticking to it. The introduction of the odd unsegmented event would help to shake up this formulaic approach. Most of the very expensive tiles could limited to a couple of high cost challenge mines, so the game would still be possible in Egypt. I think it would be well received by the players, after all I've never once heard anyone complain about the chance to get some premium equipment for their camps...🙃
edit....glad to see the phrase "region up" is catching on 😆...
