tbh it looks more like how to go even with zed and have your team win then beating him yourself. it looks like VI did a lot of the heavy lifting with Darius scaling in the background. About half your kills are gotten, after your team was 10k ahead. The only adc the enemy team had was a twitch who gave a double kill in a early gank from what i can tell.
as for the zed being a good zed mastery does not matter i have something like 90,000 on tank top Ashe where i first buy Black clever and go tank/cdr items.
The highest score Taliyah player has over 5 mil and last i saw was bronze with a horrid winrate.
His winrate is high due to him barely having any games and if you look at the few games you can see he almost always has someone mega fed with him.
"also if you look to last season he has a winrate of 42%"
For his KDA being pretty good its more then likely due to him playing a assassin and doing the "Rengar method" where you pick 1 target who you kill the fastest like a adc support mid without hourglass and jump in 1v5 dump your kit on them and they die then maybe escape or die "mostly die" it's also why his deaths are so high 14.0 / 8.1 / 10.4 is his average that's a lot of deaths.
Final for what you picked in runes and itemization.
What champion changes zeds?
What does Zed change when you pick lux or annie or talon or kayle or hell even something dumb like zac mid?
at best you get him to MAYBE buy a QSS if you go Malz or lissandra. and he will swap his one MR rune to a Armor rune.
he CAN buy a hexdrinker but from the stat site i use op.gg its one of his least winrate items along with other component items.
All of that is optional to him.
But for the inverse what is consider mandatory for mage's "for the most part"
if you don't change your runes too revitalize bone plating and buy hourglass first and maybe throw in armor boots and maybe even play a champ that is a counter to him you lose all right to complain about him.
Don't you think that's kinda dumb where just seeing zed picked not even it being a good zed just the fact that Zed is in the game means your first item secondary rune tree and stat runes are locked in for you due to Zed just being IN the game.
The only other champion's i can think of that does something CLOSE to that is malzahar and mordekaiser where they make you get a QSS sometime in the game if they target you a lot.
But hey what do i know i'm not a pro i'm just someone who like playing clown meta and i don't even thin zed is strong his teamfighting is trash and the only poke he has in lane burns his mobility. He almost like tahm kench top. how he warps the whole lane around him just by being him. not very good can't do to much but you dare try to touch him before the 15 min mark.
He just feels unfair.
Also you were a full division ahead of him and he barely plays at all now.
