Can we get more detail on skins + class release

In the newsletter it went over how skins and class schedules are intertwined. I understand the concept but fail to see why it’s the blocker here. All of these classes exist on Korea. They all have skins on Korea. Can’t we just release the class with the skin that’s available on Korea?

What needs to be updated/modeled for each class? We only have three skins even available, can’t we just release the class with a currently available skin on Korea and move forward? Are the skins being altered in some way for the western release? I’m just really at a loss as to why that is what is determining the timeline for these launches.
