After discussing with Titus, he asked me to provide examples of W3C options that remove DesiredCapabilities completely. I've added some cases for TestNG of this.

Chrome fix works fine, however the Firefox example keeps throwing this error: org.openqa.selenium.WebDriverException:` Infrastructure Error -- The Sauce VMs failed to start the browser or device.

Can't quite figure out what the reason is, I tried modifying .setLegacy() thinking it was forcing marionette driver but that wasn't the case. I also tried disabling "w3c", true but no change.
