Original Champ Riven Does Not Receive Gold Chroma

As stated in the title, the original Championship Riven Skin does not have a golden chroma able to be purchased, despite there being one being found on the PBE. I own the the original skin, and it feels pretty bad that I'm unable to show off any worlds hype through the skin I actually like using. I was actually beyond happy that I potentially had way to double-down on worlds related content, as I had been playing for a fairly long time. I know a lot of you may not care due to being locked out of that version of the skin, and while I can't really blame you for it, I feel this is just as odd as one of the championship skins just not receiving a chroma at all while the others did (for example, Zed being excluded). I honestly wouldn't even mind having to grind more tokens in order to get the chroma. As sappy as it is, the OG skin holds a lot of good memories for me, and I would greatly appreciate being given the option to upgrade it like the rest.
