I highly recommend this merge request. I also faced similar problems while trying to use ScrollMagic.
However I somehow got it working by ignoring those files in .babelrc file like this

{ "presets": ["es2015-without-strict"], "ignore": [ "bower_components/justgage/raphael-2.1.4.min.js", "bower_components/scrollmagic/scrollmagic/uncompressed/ScrollMagic.js", "bower_components/scrollmagic/scrollmagic/minified/plugins/animation.gsap.min.js", "bower_components/scrollmagic/scrollmagic/minified/plugins/debug.addIndicators.min.js" ], "compact": false }
In above code snippets I used "es2015-without-strict" to use raphael.js library. As it turned out raphael.js can not work while "use strict" is enabled
Please consider this merge request so that people like me won't have to waste time trying to figure what went wrong.
