I do see the compromise, the large robot has what? 14 points of articulation, where the G1 Bomb-Burst shell had 2 points. Sadly the inner robot went from 7 points of articulation to 4. I like the idea of figures made all of 5mm ports and pegs that break apart. See, as an alternative to ball joints, you can make some articulation in a 3 inch tall figure just be using 5mm pegs and holes. We saw it in the Micronauts Giant Acroyear figures. The elbows, knees, neck and waist were all 5mm pegs, the hands were 5mm holes, the legs had 5mm pegs in the sides. These figures had 10 points of articulation without any ball joints in 1976, all 5mm pegs! Looking at D-Throne, it looks like you could at least copy the knees and waist articulation right off the Micronauts figures. Arms and head might be tricky considering the design. But that's 3 extra parts for 3 more points of articulation. Taking him back up to 7 points of articulation, and adding 5mm ports, which means it's an improvement over the G1 toy.
