I read and saw somewhere appollyon having a tiny swivel in his waist. Combine that with overall tightness of the toys joints (except the ball joints)... Disaster is bound to happen. Same thing with TFC constructicons. A lot of the swivels were designed too small.
Same with CW voyagers... All that to accommodate the right aesthetic.
I've seen a great solution in past iterations but have been abandoned probably due to complaints of parts popping off, in relative safety of course and in favor of not breaking the parts.
I first saw the warning sign in my first TF purchased as an adult. Years back. I still appreciate the design to this day.
I've heard and read some mushroom pegs breaking off. I own so many alternators and never broke one.
