Trade and fleet labels do not map cleanly onto cruiser gun size

Would classifying cruisers as trade and fleet types work better than light and heavy?

Not cleanly, because 8-inch and 6-inch cruisers each serve both roles in different ways.

Replacing light and heavy with trade and fleet appears to offer a role-based classification. The roles do not align neatly with caliber, however. An 8-inch cruiser may be better for independent trade protection against a surface raider because it carries the heavier hitting gun. A 6-inch cruiser may be more useful in fleet action because it delivers greater volume of fire. Simple paired labels can hide overlapping cruiser missions rather than clarify them.
