And yet my iPhone 5 ran 8.0 perfectly fine as well as my iPad Air. I've since sold both of those devices, but I imagine things have only improved since then with 8.1, 8.2, and 8.3. Not to mention, the latest poll on this forum shows that a majority of users are indeed happy with iOS 8 now.
So no, people don't need to be made "painfully aware" of something that may or may not happen. Of course, every iOS device you use seems to have dozens of issues with it, so I can understand why you feel the way you do. But you've been told time and time again that your experience is not the norm.
Before anybody jumps down my throat, I'm not discounting those that have issues. I do think that a higher percentage of users are experiencing issues with iOS 8 than past versions. But it's still a small number of users outside of forums like this one where many people visit for the sole purpose of troubleshooting their problems.
