Calf swivels suck though, you won't get an argument from me there, the only time they're acceptable is when they're hidden by a boot sculpt.
The frustrating thing with Hasbro is that they've got a solution, they've used a similar ankle joint to MAFEX in the past, on figures like Doom, modern Moon Knight and BAF Apocalypse. They just refuse to widely implement it.
