Yes, it is realy tiring, and wasting time !
C2 is such a large area with so many countrys, and some Locations are also unclear belonging to which Zone as TLV or DME, so it would be helpful to define the zones in smaller Areas.
As already said if someone post C2 - C3 it could be everything from IST-NRT until DUB-MLE
