As someone who knows a handful of Jett mains and as someone that very recently was considering side maining Jett as a future bossing mule, this is heartbreaking.
Nexon, please stop saying you're going to do better and communicate with your players in the future and never following up on it. Just actually communicate properly and let us know your end goals or give us some kind of heads-up that isn't quite literally while the game is down to let your players know that Jett creation is no more.
It's heartless and the past year of decisions y'all have been making just hurts and soils the image of this game further with each passing update. With things like Commerci transposing, Silent Crusade, totems (you even got caught using totems in your PB/Yeti promotional video recently before you silently reuploaded it and cropped it out weirdly), and now Jett being removed, to potential future ones that people fear such as attack speed 0, and Gollux. We know it's an inevitability at this rate and no community wants to be that pessimistic and left feeling pure hopelessness for the game that they love.
I refuse to spend money on this game anymore until we get proper answers and communication that isn't same-day. Patch notes used to be up a day or two in advance of a major update and now we don't even get that anymore.
I do not blame the translators or the CMs for any of these faults, and neither should anyone else. This falls squarely on Nexon to do better.
