Not even slightly. The fact that it's not possible to get old collab skins is an astonishingly bad business decision. Darth Vader is locked out forever, are you fucking kidding me?
Yes. the idea of scarcity/rarity is what makes my family pay for the battle pass some seasons. If the rewards of the pass aren't enticing to us, we don't bother. If we spend money and grind, only to see those skins for sale, it's a betrayal of sorts.
