There is a huge difference between saying "the 7D MkII has a number of issues" and an individual 7D MkII having a number of issues.
I don't see any evidence of the 7D MkII line having issues like the 1D MkIII, D600, 5D MkII, D800, Sony A7 etc etc, that are based on faulty design or manufacture that result in most if not all bodies suffering the same problems. There are many reportsof unhappy 7D MkII customers but when you drill them down many ownes don't know about simple processes like AFMA, for instance.
Now I am not saying East Winds particular camera is not a lemon, every production run of everything has a lemon or two, but that is quite different.
Well I'm finding quite a few people here as well as on canon forums all complaining of the same things and it's not just afma calibration. I am very experienced at that and I can assure you not everyone's issue is a failure to afma their camera to their lens. Not sure if it's a bad batch...mine was serialized less than 100...or what. Only canon knows what's going on right now.
As I said before most if not all could be fixed with a firmware update as I don't think there is anything physical at fault. Be it bad software or just bad factory calibration. There is enough people having the same issues that it's not just a camera having multiple issues.
If yours works for what you need then great. Glad you got one from a good batch. Or perhaps you just haven't discovered the issues yet or have not really looked at the numbers yet to see that the keeper rates are piss poor compared to other bodies including my old t2i. It is not a little brother of the 1dx. More like a big brother of a 7d with shorter battery life.
