If you complain about Leblanc but not Lee Sin

Lee also has the privledge of building zero damage items and still owning carries late game. He becomes incredibly difficult to take down late game because even if you catch him, he has extremely high survivability from his build path, and he has built in sustainability so even if you do break his defenses, he can heal it back up and keep on going. LeBlanc has to build 100% glass cannon or she is completely useless in every single way. She also dies if you so much as sneeze near her, and has zero sustained damage after her combo, and if you hit her, the damage sticks until she goes to fountain or dies.

It's so silly to only focus on a champ's strengths and pretend that they don't have any weaknesses at all, just because it's what everyone else is doing. She will fall out of favor with the new meta, but she'll still get nerfed because of people who can't think/play for themselves and be replaced with a champion 50x more annoying/powerful than LeBlanc ever was (Ekko).
