I personally don't think G1 1984 Jazz is that bad, but he's my least favourite of the first year Autobot cars -- and the one I never got as a kid (my G1 Jazzes are reissues).
Not really. While Binaltechs are rather complex, their transformation schemes are usually reasonably intuitive, whereas Wheeljack and Grimlock are - as kurdt_the_goat said, counter-intuitive. I find other BTs' transformations to be complex, but satisfying and worth the effort, whereas with Wheeljack and Grimlock I just find that the end result isn't worth the effort put into transforming them.![]()
