Wings are a main event, not a true appetizer.
Calamari is the classier mozzarella sticks, both are great.
Wings, like a quesadilla or nachos, fall into the category of food that is amazing and can be either an appetizer or a meal or sometime abundance.
I concur and this is where a I disagree with @Doogles . Yes, you feed an army with wings. But they are still appetizer first and foremost.
