I stand by my original opinion on this.
If you don't like Ri3D or Buildblitz, your team and your team alone has the right to decide not to pay attention to BuildBlitz/Ri3D and all resulting designs and CAD models and videos.
Just because there's a bunch of violence on television does not mean that I have to watch it. Similarly, if a team decides that it is preferable to design in a vacuum, that is their right.
Personally, I don't see where the obsession with creating unique designs comes from. FIRST robots have always been a combination (in various degrees) of previously existing technologies and game mechanisms. Build Blitz/Ri3D just happen to be introducing more relevant mechanisms (none of which, by the way, are really anything new-- winches and catapults have a had a large deal of previous use in FRC). The only mechanism that I saw that I don't think is relatively common knowledge (other than Boom Done's awesome use of sensors) was the choo-choo mechanism of Team JVN. Roller intakes are classic, catapults were used in 2008 and a little bit in 2012, winches have been used in 2008, 2010, 2013, at least, and motor-powered flingers (like Boom Done), while not exactly common, are really just an extension of a classic arm/lever design.
Individual mechanisms very rarely in themselves grant teams advantages. It's integrating, effectively implementing, and quickly building mechanisms that is the real difference.
Borrowing designs is not a bad thing. There are no patents in FIRST robot design (at least by teams).
