From what I saw, what you guys were asking for with PROJECT: Jinx though was a bit too much, though. You were asking them to completely scrap and re-do the skin the way you wanted it to be, completely disregarding the creative approach the skins team took with the skin just because you thought the fan concepts were better(they aren't obligated to use fan concepts with every release anyway, so you guys should have never gotten your hopes up to begin with).
Completely re-doing the skin is something they can't do after it is placed on PBE. You're asking them to erase and re-do months of work just before the skin's launch. That's not going to happen. If the skin was going to get redone, it was going to be in the initial, internal testing stages, before it even hit PBE, because that's the only time they can make such drastic changes, and even then they might not do it due to time constraints. They have a schedule they have to follow, after all.
