Even with the examples you mentioned, the distinction between Vanguards and Warden's isn't one of CC or defensive capabilities (all tanks tend to have both), Disruptors aren't a class anyone invokes, even in terms of contribution (which is area denial, not CC) when playing League, and Riot lists Enchanters as characters who empower allies, instead of protecting them. Even if you just want to bring things down to labeling, which ignores a huge part of the issue being discussed, there's still a problem with labeling things improperly, and we're back to a point where one part of Riot's design philosophy doesn't match up to another.
