All you have to do is backup, flash, update, restore. Simple as that. You know that with 8.1 your app settings and start screen gets backup up as well right? (well most apps).
Have you actually done it, or just talking in theory?
No, not most, SOME app settings get restored! Many still do not backup settings, probably 15% of mine did. Even Big name apps such as ebay, amazon for example, you have to input username/password/settings. If you have lots of apps (as you might do if you leverage the full potential of a smart phone), there is an awful lot to do. Start screen gets restored. Some contacts don't get linked. Apps get reinstalled.
I did mine a couple of days ago, and to backup, reset to 8, update, restore, and then get everything working again as it was, took 6-7 hours. Some people just don't have that time.
I will say, however, it was worth it. We all know a refresh/reinstall on a PC improves things. It did on my 1520 - battery life has increased by 5-10%, things seem faster, and the phone heats up far less whilst doing the same things. No doubt Cyan helped, but it can't account for ALL of the improvements.
There are people that dispute this fact, and claim that if a reset does improve things, it means the OS is rubbish. Not true. Think of all those apps you have installed, some written by inexperienced developers, updated a few times - is it really that impossible to imagine they might introduce small issues fixed by a reset and download of new version also?
If you can get and want cyan now, and see the benefit of a refresh, then downgrade now. If the answer is no to any of that, don't downgrade and wait for the fix (however long that takes) and quit whining!
