Leblanc is really badly desinged.
So firstly ima tel you that i main mages and mid lane. So by that i need to face a lot of lb-s. And i just cant win lane aganst her. And you can say that im bad or something, which is maybe true but consider the fact that i was Gold IV last season im almost lvl 5 with all of the mages in the game and i have like 2k hours in the game. There are a few champions that i have trouble laning aganst like fizz and zed. But i can outplay them(even if its hard). But i can't really do anything aganst lb with any mage that i play. And i play all of them.(Also most of the time she picks it aganst me so i cant really counter pick, but thats just a coincidence.)Most of the time she can kill me at like lvl 4 or 5 by jumping on me, using her combo and ignite. And if i somehow survive thats becuse she missed her E and/or i used my summoners. And yes the preseason hit her hard, so she can't do this...at lvl 2 now like she used to do. I can take barrier, heal, exhaust its aint helping. She just jumps on me and im dead. She even hard to gank, so my jungler cant really help most of the time, since she can just b4 we can cc her or after we cc-d her(and in laning phase we dont have that much burst to kill her while shes cc-d). The only thing which can save me is a zhonyas since i can block her combo. The problem with this is that if i do this she jumps back and does the same, except i dont have zhonyas so she kills me. Even if i somehow win(i get carryed by team mates, or i can catch up late game) i never enjoy a game where theres a lb in the enemy. The most frustrating champion in the entire game.
