What position and champion can you absolutely not play?

Lee Sin. I see all these high-caliber combos with him dashing everywhere, but when I play it just looks like a cat jumped onto my keyboard and is trying League for the first time.

Also, Azir. Shurima Shuffle? What's that, some sort of card trick?? I also can't operate his sand soldiers for anything. I always end up misclicking and walking forward rather than using them to attack from range.

So far I can play all the champions no problem However I get very bored playing adc so I generally avoid the role I prefer playing tanky champions so that sometimes interferes with my gameplay ( I somehow think heimerdinger with full ap can tank lmfao )

I can effectively play most roles, I just won't make as big of an impact from the jungle usually. As for champions, for me it's Kalista. I just end up jumping into trouble because I lose track of whether I'm clicking to auto attack or clicking to jump

My worst role is adc, my worst champion at adc would be Vayne

I can't play support, i can, but i never get reliable ADC's that can secure kills when i make plays, so i end up having to flash and get the kill myself and then get bitched at by the ADC who is still casually csing instead of killing the people i just double stunned and took half their life.

So i avoid support for that reason xD
