A malphite ult without the knock up lol. So just pure damage. And it's got not nearly the range, and much slower. Her E's hit box is already dirt thin, and her mana costs are quite high to compensate for the free mimic.
I'm not saying she's a bad champion, not at all. But she doesn't need nerfs with her current state. She's not nearly pick/ban, her percentages are low. You don't nerf champs because they're popular and played a lot. You nerf because they are inhibiting the fun and fairness of the game.
And not relying on mistakes? Don't give me your condescension with "boy" and try and discredit me. You know -nothing- about Leblanc if you believe she doesn't rely on mistakes and over extensions anywhere past early-mid game. Her "malphite ult" as you throw out of proportion is not simple enough to just jump in. CC exists, human intelligence exists.
She lacks reliable CC, and makes up for it in heavy damage and mobility, however the reliability of damage falls off the longer the game goes.
I admit getting dumpstered by a Leblanc feels shitty and counterplayless. But that's how assassins have always been. She's an early game dominant bully that works on a clock that is slowly ticking down.
Now this proposed nerf, or rather clarity change isn't huge and honestly wouldn't change anything, because knowing the range is irrelevant really as its up to her whether you get out or not, it's still unnecessary in her current state. If you have mobility, you'll use it and get out of the range. If not, she chooses whether she wants you snared or not.
Don't demonize point and click. It's a two part spell so point and click is kind of necessary. If Leblanc's point click combos are an issue, then tun your attention towards Annie, Ryze, Akali, and many more champs who have very similar skills.
Balance isn't done around solo queue barring complete stomp champs that show a dominant trend for a long time. It's done around pro play, and Leblanc isn't dominant there.
Also a side note, this would actually be a buff to a Leblanc as I just realized. If there is a range indicator on the enemy, you'd have to give one to LB too. And you don't want her knowing exactly how much range (1000) she has.
