Why is Zed considered hard?
I've heard so much about how Zed is a high skill cap champion over the years. Never really played him. Recently I had a bunch of IP saved up and I said "Hey, I'll buy Zed just to play in normals, that should be a fun, challenging diversion and it may help me improve my mechanical skill". I played one custom game, then went into normals.
Very first game I played against people, I would just press R, mash buttons, then delete the adc. Like every time. Any time the ADC tried to get near a fight: R->buttons->kill. Sure, I felt totally useless when my ult was down. But I carried that game by taking the adc 100-0 every fight, and it felt like it was free, I was not doing any work to get these kills.
Maybe Zed has a lot of potential in the hands of a great player, he has a high skill cap. But he also has a high skill floor, he's very impactful even in the hands of someone who sucks with him. You do not have to execute his combo perfectly in order to straight up murder squishy targets until every last one of them buys a QSS or Zhonyas.
