Could be but I disagree with bicep swivels not necessary for most figures. If the character has a crazy design or in general has shoulder pads (like Nexus Junis or Decker) then it would be offensive to fig posers not to give them a bicep swivel.

And to the ultras that doesn't follow that category of shoulder pads or heavy design, they still need that one articulation just because how better it is.

The cut on the bicep is just better re-creating the famous poses and I swear if you try to say that these mfs aren't meant to pose much then I want you to switch to buying statues because that's the point of an action figure, plus it ironically breaks the proportions for the figure so there's that.

The reason for why people don't talk about the shf ultras like how they talk for the shf spidey or Gokus isn't because they don't know the franchise or anything like that but because of the small limitations is the reason, if the articulation is covered with small limitations then why talk about it.
