Well let's start, lately I had several problems with the limit of vinyls, have all the layers unlocked (23 in total) and with premium (30), good to have 30 layers of vinyl sometimes is not the best as it limits the vinyl creation with many details and I think you could add at least 15 more base layers (unlockable with task points) and another 5 more when buying premium, this from my point of view can help some people to create vinyls with many details, Obviously this will give drops in fps and, therefore, I suppose it should be optimized before being implemented, but at least it is a positive idea with respect to the vinyl system itself.
(Also, I've seen other users complain about the same thing)
From my point of view, it is not a bad idea, since it contributes with the vinyl system and offers many more possibilities to the vinyl with more details.
