PSA Riot has no information on the LeBlanc Changes Right Now
I am constantly seeing people ask Meddler in his gameplay posts if they have anything when he has said over and over that they have only just begun work.
I suspect Meddler will briefly talk about the update and give us little insights similar to how he did with Rek'Sai.
All you're doing by asking is discouraging him to reveal early work because it sets an expectation that it's soon.
So please, give them time and stop asking.
