Having spent some time with Protractor and strong believer of the importance of writing tests, I think that writing end-to-end tests for a complex web application is quite hard and you will often end up spending more time for testing compared to writing the application code. Currently, my approach is to monitor the web application in real-time with a real error tracking tool such as Sentry and deploy the new versions of the app to a specific user groups for initial testing and eventually make it available for all users.
