If you don't like Launchpad, don't use it. Believe it or not "Applications" is still available from the Go menu in Finder, or you can add Applications to a stack on your dock.
There's no need to disable it.
There is a need to disable it.
Removing it from the dock still brings it up when an application is downloaded and installed via App Store.
