Yes and No. There's a nuanced counterargument.
You do realize most consistent feeders are due to outright counters?
Yes..... there are your run of the mill "I can do anything" yoloers.....
But then there's people who are in a fight where their lane opponent has a massive 73% Win rate in the exchange with the champ they are playing, because
a) They are a pure counter to a kit
b) They can turret dive safely
c) Their jungler is helping them
d) Their laner is a smurf, and the only way to subjugate that smurf, is counterganking.
I Rarely ever feed. However, it does happen.
About 12 games into this season, I was Zyra top vs a Yasuo who was D II smurfing in Gold. My jungle duo had computer issues at the time, and was getting bugsplat in that game. Basically, 4v5 with no jungler.
All it took for the Yasuo to completely dominate my Zyra, was for his Vi to gank level 1. They didn't kill me, but they did make me recall.
Instant level 1 vs level 3.
Not only that, but the Yasuo was perfect at forcing. He would set up a wave to where I had to step in Q range to actually farm/last hit something, in a specific location. If I didn't I'd lose the entire wave. If I did, he would release a tornado the very second I was about to start my auto attack animation. And he always released from a position where I couldn't walk left or right and avoid it, because of the way the waves were constructed in blocking me.
Later game, he began trick shotting. When I had to recall, and walk back to lane, he'd go take our Jungle Gromp, use it to charge his Q, and as soon as I walked past my first turret, I'd get Q ulted across the wall, before I was even in Ward range. He likely even used Flash to increase the distance on his Q.
I would call this a pure counter. I needed jungle help. I didn't have it.
