My thoughts on the Dinoforce (individually and as Dinoking):
Overall impressions are great. They are a wonderful little team of dino dudes. The colours are on point and they have fantastic cohesiveness. The packaging is fresh and retro. I got mine on a Black Friday sale at an amazing price.
Goryu: Great colouration, nifty dino mode despite the back chunk (his legs in robot mode), good looking robot mode and head with okay articulation.
Doryu: Dino mode a little compromised but second best robot mode. His colours work well, great head, great articulation.
Gairyu: Second fave dino mode, I love an Anklyosaurus. Little squat spiky dude. Dino mode a bit unbalanced without his weapon but still looks good.
Kakuryu: Back end of his dino mode a bit compromised (shoving the combiner head up his butt would do that); very sharp robot mode although limited in articulation.
Rairyu: Probably the most compromised and least favourite pick. Both dino mode and robot mode are pretty meh due to his need to be a bottom torso. Robot mode transformation is pretty ick, slightly improved by attaching his rocket launchers; also improves his stability.
Yokuryu: My absolute fave. I love this guy. Amazing articulation not compromised by combining ability and looks sharp in both robot and pterosaur mode. Thinking about tracking down core class Swoop because of him.

Dinoking: This lad is pretty damn sweet. I managed to get three of six limbs correctly transformed just with reference pictures which always makes me happy when I don't need instructions. Stable, poseable, and his combined weapons are fantastic too. Ready to stomp your face and not apologise for it.

I'm very pleased with the Dinoforce and Dinoking. He's made me love dinosaur themed transformers again.
