Of course she can still be opinionated, but the question is at what point does an appearance change so much that it's basically a retcon, because it changes your entire perception of the character.
MKX D'Vorah was totally rocking a haughty, regal "I'm too hot for this shit" bitch vibe. Between her animations, her black lipstick, her necklace, and literally having biological high heels, you can't tell me it wasn't all creating a certain impression. With her new appearance, I'm not seeing how she pulls that off. She looks more ready to crouch down on all fours and pouce than to walk around like she owns the fucking royal palace.
I'm not saying I hate this redesign. I'm keeping an open mind. Maybe after the disaster that was Shinnok's defeat, she canonically devolves into some kind of bestial form and goes into survival mode. I dunno. I'm just not seeing how this design makes sense with the scenes she had in MKX.
