There's a healthy middle-ground for LeBlanc.

So back in her rework, people just whined about how her kit was, even though the balance was good.

And now, people complain about how mindless her instakill potential is. Just a W R W, haha bye health bar.

Why not just,

#Lower her W damage and put her ratios elsewhere?

I personally would LOVE to see her dash move do literally 0 damage, so it would only be used for utility instead of being her go-to "I'm not very bright but hey this seems to work" combo. Of course, let it proc her Q as well. But that's it. I always believed that LeBlanc's assassination combo should go something like E Q R W. Tethering/rooting someone before plopping her sigils for the damage would actually give her a requirement in order to do her damage, instead of POOF POOF dead.

And if it does no damage, you could make using her ult to dash a second time halve her ult cooldown, too. Just for all the more utility. Like an actual trickster!
