i could keep explaining to you how, but you won't listen, in the end it's you... considering ADC's aren't even the strongest spots, the only thing you've shown is that you get kited... along with the graves one being a bad example considering he gets bonus armor off his E
By the time one tentacle gets through the animation an adc would get around 2 maybe 3 autos off and then I'm sure you got kited from there on...
You described a lategame renekton whose damage falls off, lulu mid who nerfed out the wazoo, besides a lulu is never able to 1shot an adc not mentioning the fact that Maw itself is a strong item on it's own.
Illaoi, really? are you actually trying to say you're going to oneshot an adc with tri/steraks. Not even going to explain the illaoi one.
Show me the renek one vs graves. besides graves being one of the beefiest adcs. adding to his armor with his E(which stacks up to 4 times), I doubt he ever just builds pure damage without some bulk in it. I bet he also along with his E stacks, had a PD which gives 12% damage reduction from the last person he hit. That, anddddd I'm sure he also built Deaths Dance which turns another 15% of damage into a slow bleed as well instead of just instant damage.
