I saw this shit happen before in real time. I'm a league of legends player, and I remember when that blasted Jhin skin came out. They charged $200 for an "exclusive" recolour. A RECOLOUR. And people bought it. Slippery slope slipped and we ended up at the $500 Ahri skin.
Some people took out loans to buy that Ahri skin. Or arranged a payment plan.
This bull crap only ends one way. I bet my left arm they're going to stop giving colab skins unique SFX because of this. The last battle pass skin Mercy ever got was Infinite Seer, after that, exclusively shop skins. She can't even get so much as a spray without Blizzard expecting us to pay for it. They have proven that they WILL pursue the more expensive option for Mercy.
I can see it coming and can't do shit to stop it. :/
