What exactly is wrong with Zed?
People keep saying "Zed is unbalanced", "Zed is frustrating to play against", "Zed is overpowered", "Zed is a poorly designed champ", etc but I disagree. Zed, design-wise, can be viewed as a champ made to deal with Ranged pressure and have pressure of his own. Let's look at his abilities.
Passive: Bonus dmg on one aa when enemy is below 50% hp. Basic.
Q: Projectile that deals dmg but dmg is reduces when it passes through units. Basic.
W: Projectile that is basically an extension of Zed and mimics abilities. Not Basic.
E: Deals dmg in a circle. Slows when used with Shadow. Basic.
R: Makes Zed untargetable for a short while, deals dmg and marks target. Mark stores dmg and "detonates" after a few seconds. Also spawns a shadow. Basic.
Zed's kit is the definition of a model assassin. He has engages and disengages. Pre-6 he's open to poke but can also dish out his own but at a cost. His W has a high cd and is maxed last so if he uses it and doesn't deal good poke dmg, he's at the mercy of the enemy and very susceptible to ganks. Post-6, his kill potential increases depending on how pre-6 went. His kit allows him to roam and take out targets especially squishy ones.
When I first started playing Zed in S3, his basic build was: BoTRK, Black Cleaver, Hydra, Boots, Last whisper, Ghostblade/Maw. Now how much has Zed changed? Not much. A few kit changes that aren't entirely buffs or nerfs. But look at these items I listed. There was less CDR, less armpen, No keystones, etc. Zed wasn't feast or famine. If he does well early, he could assassinate in less time allowing him to escape instead of dying. If he was behind, he could comeback. Same with most assassins back then really. But now with Electrocute, lethality, things like Stormrazor and Duskblade and the multiple runes that grant offensive stats, it's obvious that he'll be stronger than he used to be. And this applies to EVERY champ. We've seen Sorakas poking ADCs out of lane at 2:50.
What I'm saying is, instead of blaming champs for being OP, blame Riot for making changes without adequate foresight.
has been a problem LONG before new runes
which then delays your mana regen which which u at a heavy disadvantage until they have 2 complete items
if you are of any threat to him.
