I agree. When we first started teaching React workshops, we taught a 1-day workshop where we introduced students to React, Webpack, React Router, and Redux. This was all done with ES6.
Fortunately we had the benefit of selecting from a large number of applicants, and we required a brief selection examination. Most were already strong in JavaScript and many even had ES6 and React experience. So learning React & Redux, and grasping the concept of webpack and React Router was not too difficult for that group.
However if you're coming fresh into the React ecosystem, and especially front-end development on the whole, it's important that you don't try to learn all of these things at once, as many have pointed out here. Our current workshops are focused on learning React and React alone. For example, our current "build an e-commerce app with React" workshop gives you a boilerplate with everything you need, and we build out the application from that point.
We are based in SF but often travel to other cities. Our website www.realworldreact.com is under development, so you can learn more about us at https://meetup.com/Real-World-React
