Guys Please help on this one! Testimonials Addon for Fusion Builder Rejected

I just got rejected, but the main question is why I guess.

Reason: This item has a nice concept, but doesn’t feature the required functionality and features to be approved as a premium item.

The thing I will mostly appreciate is any suggestions or thoughts on the functionality described. I think my greatest mistake was that in the notes for the reviewer I didn’t explained why is different from the rest of the testimonials provided for Fusion Builder.

My main goals were:
Create Builder Element for Fusion Builder.
Simple / Light - I didn’t want to add heavy chunks of code inside builder designs because as we know they can take quite a bit to load in some cases
Simple Carousel Designs with more than one testimonial per page (visible testimonials per slide). Currently all the addons and default modules have the option to be displayed only one per slide. The designs featured are 3 basic designs for testimonials I’ve been requested many times by clients.
