As User482 says the bouncer has many uses apart from getting caught. The West Indians perfected it as a way to intimidate batsmen onto the back foot with a view to getting them with a yorker but of course you knew that really.
This 'subtlety' you speak of - is just one of the many ways cricket has of looking nice to its audience, but it is just ways that cricket fans have dreamt up to make it look a lot more difficult than it actually is.
