Why is the PvP Shadowstalker set unavailable permanently?

[MilkieTea]

There are 6 data centers: 1Aether 2Primal 3Crystal 4Europe 5Japan. Can you learn to count?

Also go find me a number that can divide 1 that isn't 1 itself. I'll sit here and wait for infinity because guess what it doesn't exist.

:P Must be a slow winter day wherever you are!
