If they keep it the same way as they did for LSM than Alt legion skins would be stupid because that would mean only 1 of the current legions ingame would get a world eater skin and the rest would get some other gods main legion. I would pity those that play the legion that gets Thousand Sons. And a lot of people would be pissed off that their legion didn't get World Eaters, Death Guard, or Emperors Children. It's better to give each legion we have god themed skins. And you'll probably learn about the squares when your older since i'm just gonna assume your like 9 years old or something at this point.
