I really was not trying to be dramatic. Quite the opposite. And after Flick left, the team went downhill, of course I'm going to blame the one constant in that story, that is Löw. Players mess up, sure, but he's the one that sent Müller and Boateng home and is too proud to ask them to come back when they are obviously in the form of their lives (still). Yes, he is the lynchpin that needs to be replaced. That's not irrational, nor is it emotional. It's just a very obvious step to take if you ask me.
As for our expectations, for the past decades we have mostly played for titles. Our expectations are neither irrational nor too high. They are dialed in absolutely correctly. We expect our team to reach the semis at least, if possible play for the title in the final. And if you look at the German NT you will find that we have the highest attendance in finals, our points in WCs are only surpassed by Brazil and there are endless more statistics to support high expectations. What you're doing, however, is typically German in that you shittalk your own team despite it being good enough to win any title. Not sure why people do that. The German NT isn't England, people actually care about the NT here and the NT is actually decent enough to be a title contender in every single tournament. (Sorry to my English friends here, but you know it's true, you care much more about club football than your NT).
Things like Russia are massive outliers. And losing against Macedonia should be an alert signal. I don't care if they have good players in them, I'm sure they do. But it's still freaking Macedonia.
To put it into perspective, I'd expect France or Spain to be able to beat us. That's it. Anyone else on the planet we should be able to handle right now. And before you ask me "with what team?" I'll remind you that there's a reason player prices spike after tourneys. It always amazes me that people don't understand that big player names are made at tournaments, not before. So even if you don't think they rate highly, wait until they perform decently at a tourney and then you'll go "Well, of course, with THAT team we ought to have reached the semis easily..." yes, well nobody ever said that during qualis... funny how that goes.
