There is no reason whatsoever to pick LeBlanc anymore, just pick Malzahar.

He's better at farming and lane clear. He's better at 1v1 and overall damage output. He's better in team fights. He has an AoE silence and single target suppress whereas she has a measly immobilize if you land the chains.

Thanks for ruining her Riot, she was absolutely my favorite champ before everyone starting playing her nonstop and you nerfed her into unplayability. The only thing she has is mobility but a little magic resist and she is toast. Thanks.
