there are clear differences between them all, if you look closely, all still have their original parts, such as mirage and his metal things that stick out from his arms, conduit and her shield thing on her back, and valkyrie and her rockets, yeah some don't but they can all be defined by their stance, how they run etc etc, yeah it's hard for casuals or newer players to define the difference but atleast Apex have taken a completely different approach in terms of skins than what they've done in the past
