The problem with those really articulated poses even if they are possbile, on the Batfleck figure for example, you'd likely encounter damage if left in those positions for very long. The only figure I have that I feel confident leaving in strong action poses for any length of time is the Spiderman 3. Ironically the one pose that is difficult for him is standing up due to his weak ankle joints.
Armoured Batman has next to no articulation but I love the figure in his museum pose. WW should be much better articulated than that but yeah, if you want to pull off all the crazy action poses she did in the movie it probably isnt the right figure for you. I just want her stood alongside Bats & Supes holdng her sword and shield ready for battle.
