The composer they use is very complicated, you spend a lot of time working on it and also you have to scroll a lot even that I have a 4k display. If this theme had the visual composer as a default editor I would rate it with 5 stars.

Thank you for your feedback! If you check the theme's change-log you will notice we are constantly improving the framework including the builder. The reason why we and most of the top authors ( Avada / Enfold / X theme ) have their own Drag and Drop builder is that we have more freedom when it comes to design. Even though you can customize any part of the Visual Composer in theory in practice it has limitation that can not be overcome easily and most of the authors that have resources develop their own builder. We understand that for people used to working with Visual Composer, a new builder may be stressful so for nearly 2 years now all our themes are fully compatible with Visual Composer. My guess is you haven't been aware of this.
