Isn't that the same with most 3P and even some official MP TFs?
The saving grace of most mainline Transformers is that they have to
transformable convertable by little kids. That keeps the designers and engineers honest.
They even scaled back difficulty when they admitted, post-DotM, that the movie stuff was getting a bit too complex for kids.
I think recently the mainline stuff has been on a role in terms of accessibility. CW stuff was all very simple by design but they still pulled off a number of great figures. TR and PotP's stuff wasn't that difficult and still worked in headmasters and powermasters. And the WfC/Legacy lines have hit a really good balance of quality with straightforward engineering. Even stuff that seems to make magic happen like ER Optimus or Kingdom Cyclonus have simple solutions that go long ways in transformation.
The problem is when you remove kids from consideration.
"We're making toys for the adult collector" has always lead to overthinking stuff in the worst ways, be it from HasTak or 3p companies.
I don't own any MP TFers anymore but I do own the two Brave MPs TT did and while I like them in all their end modes the transformations are entirely unpleasant. The thing is that Exkaiser, King Exkaiser, and Dragon Kaiser are not complicated designs, yet these toys go out of their way to be as intricate and complicated as possible because "it's an adult collectable."
And while I don't collect MP Transformers, a quick look at reviews of TT's latest MP offerings shows that mentality is still alive and well.
Of course 3p companies fall into the trap as well. Some of it is, admittedly, about trying to copy the feel and aesthetic of existing official MP toys. And you have some companies like BadCube who base their entire brand around having challenging transformations.
But I've seen enough 3p figures first hand that neither qualification would apply to that still had frustratingly intricate and complicated transformations because that's just what's expected with "aDuLt CoLlEcTaBlEs"
It didn't always have to be this way, of course. I had both the FansProjects UM upgrade kit for Classics UM and the Rodimus Prime upgrade kit for Classics Rodimus. Neither of those were overly complicated. But ofc the same company overthought the problem with their 3p Springer figure. And Mastermind Creations' Nova Prime was downright unpleasant converting from alien truck to robot. Far too many small pieces on ball joints that had to align EXACTLY right for anything to fit together as intended.
Again, not complicated designs. But take away the guardrail of "kids need to be able to have fun with this" and designers and engineers lose their minds, thinking simple and effective solutions don't cute it because "adult collectables" require complexity.
