Go to the store.
For 900 keys or so you can buy Caira’s Phoenix Weapon Skin.
For an additional 900 keys you can buy Quantum Caira’s Weapon Skin…which looks exactly the same…
I think it’s really hard to justify selling two separate items when they look exactly the same. I can understand when the reworking of a character doesn’t change weapon models (though to be honest, they totally should). But if that’s the case, I think they should be considered as owned if you bought the same skin for the original character. Or something similar.
I had previously bought (paying real money, mind you) Caira’s Phoenix Weapon Skin and I just noticed this. I think it merits a degree of rethinking.
