Most complex transformers by class

Hi, what I love about transformers is their complexity. And with the current trend being a split bewteen Takara making more expensive and complex transformers for collectors (MPs) while Hasbro makes less complex transformers for the general public (the entire AoE movie line mentality), I thought it would be fun to look back on the most complex transformers released by Hasbro, by class. Also, simple rminder, complex means the intricacy of the transformation, not necessarily how hard it is to peg some parts.
Scout/Basic: HFTD Breacher takes the cake for this one. He has over 10 steps for the transformation and that is more than many deluxes ou there.
Deluxe: I guess a lot could be here. Though I really wonder if thre is a transformer out there more complex than Generations WFC Optimus Prime (cybertronian). This figure is insane! Everything is done so that panels connect in alt mode, covering his entire upper robot torso but instead of it being a shell former, the panels are found dispersed in smaller sections all across his forearms, shoulders and back. Very intricate. (Honourable mention: First edition starscream is the most complex deluxe Flyer transformer)
Voyager/Mega: I am sure people are going to mention Mixmaster here but I am not sure about him. It's odd but as complex as he might be, it still looks like a mess once it is transformed. What I mean is the complexity didnt really add to the figure and the figure is not better because of it. I find Binaltech/Alternators Grimlock far more interesting as a larger complex figure of the voyager class size. I have the binaltech version and the booklet it comes with makes you realize just how many steps are truly involved. And he looks nice and solid in his robot form witha very classic transformer look (though not a classic Grimlock look per say)
Leader/Ultra: I know ROTF Optimus is a given but after having transformed him a few times, I am seeing that the only part that is "hard" are inserting those chest panels. That doesnt make him overly complex, just a bit more annoying (and it's worse when transforming back to alt mode). I actually find Sentinel Prime far more involved in his transformation. The heels of his feet alone need several steps. And the way the front section of the truck becomes the chest takes as many steps as it takes to fully transform some voyagers class toys out there. I really love how he first appears to be a shell former but slowly reveals to be more than that once you start transforming him. Unlike the voyager version of the figure, his back does become the cape as seen in the film, making him very screen acurate.
Let me know what you guys think are the most complex figures out there.
