So you want a transformation that's overcomplicated just for the hell of it? For the MP line, they want to make both modes look as accurate as possible. That's all they care about. If they need a complex transformation to achieve that, then we get a complex transformation. If they can do it with a simpler transformation, then we get a simpler transformation. Much like MP Grimlock, due to the design of the character there's only one real way to do the transformation and get both modes right, and that means staying fairly true to the original G1 toy transformation. They are not trying to dumb things down. They're achieving the goal of the MP line: accurate alt mode, accurate robot mode.
