Yes, we have currently a lot of pieces that are sufficient for any number of builds. But we still havent reach to what the whole system can do and that is the unity of ccbs and technic and add in bricks to it as well. They are still some compromises and messy connections that can be fixed if a perfect mold was made.
For example: The smallest of pieces, the friction add-on helped so much in retaining stability of larger sets where as before you needed to constantly add on more connections just to make the leg area more stable to even hold on the entire upper body. Now sets like Grievous and Destroyer dont need what Fire Lord once needed, they can do it all with just friction add-ons.
What I love about moccers in general is that they dont shy from using LEGO pieces from all themes for their builds and use them in very creative "outside of the box" type of ways.
First LEGO should hire some moccers to work for them in building sets (which I believe they did to some extend since these new sets from G2 feel like they are done by fans who know the line and know designing sets and making unique builds), they are the innovators that will point out new potential moulds that can be created..............and of course they should hire me for team management who will retain the positive outlook of things (I can get REALLY passionate about things I truly want to do and do my best to accomplish the task upfront of me), lord knows I need to use my AIESEC experience somewhere right.
