There is more to Class A than the short definition.
"In a class A amplifier current flows for 360 degrees"
A class C amplifier meets that definition, there is always some leakage current flowing.

If you take the time to read the Radiotron Designer's Handbook and Tremaine's Audio Cyclopedia (and read beyond the short definition) you will see that with all of the examples of Class A (and a lot of the discussion of Class A) the bias point of in the middle of the "most linear part of the dynamic curve". You will also learn that with Class A the input is limited as to not drive the device into the non-linear regions (saturation and cutoff). Again, with Class AB the device is ran into the non-linear cutoff region (if not biased there to start with).

I don't know how you call that Class A.
