Mostly out of curiosity. Don't take the whole thing too seriously, I'm just interested to see what the playerbase finds frustrating.

For me personally, I can't find any way to deal with Leblanc, her combination of mobility, cc and range makes it feel absolutely hopeless whenever I see her. It feels more like I'm at the whim of my opponent being bad rather than myself doing anything good. I'm a Top Lane main.
Hopefully we get some fun discussions outta this. I'm not looking to start a salt war, just some lighthearted fun.
