I agree. As stated in the original post. This is more of a technical preview than a representation of the final product in regards to assets. As it stands, we have been purchasing stock content from the wonderful creators in the marketplace to help remove specific Epic created content.
Other than that, have you had a chance to play the game? I plan on dropping version 1.3 release preview anytime now and if there are small changes that are needed, that would be awesome to hear about! Thanks!
