I'm a big fan of Grievous, or GG, as I call him, but I'll forever be bummed about how they nerfed him for the movie. Like, yeah, the 4 arm thing is cool, but hot damn, is he a badass in the cartoon. Even in the CG Clone Wars, he has his moments (though I feel like they're completely undone when he gets defeated by Gungans). Oh, my poor GG. A one-man Inquisitorious.
I'd have loved a Durge in the Clone Wars line. Hell, I'd still love one. I think he's been fully relegated to Legends status now, but he was still such a damn cool character in that original show. Another unstoppable force, somehow stopped by the ultimate immovable object, Obi-Wan Kenobi. I know a Durge figure would have to be at least a deluxe, but I'm cool with it, especially if they can throw in a tentacle arm or two.
