Unpopular Opinion: Zed's not broken or OP
He's just unhealthy in design.
- If he all-ins you (and hits stuff) it's just a numbers game, as in you either will survive or you won't, and he's consequently either worthless or he feels awful to play against
- Item variety synergizes with him, from his bork days to his youmuus to duskblade, but does not synergize against him, as in hurr durr get seeker's armguard This makes him difficult to balance. If he gets solo-shut down by zhonya's, he's going to be pretty terrible. Consequently, hhe feels balanced around this counter item. The result? He feels super strong UNLESS you get the item, and even then he's pretty okay
- The massive passive steroid on his w doesn't feel engaging, so it's a huge hidden-ish stat
- Energy means his waveclear is consistent and he doesn't have to juggle resources. Shen is balanced around this with punishingly slow waveclear, same with akali and kennen, who make significant sacrifices to stay ahead of pushing.
- He's got two blinks. Being slippery is something that can feel good to use, but it can get pretty absurd and draw a lot of admonition (read: Fizz, Lee Sin)
Number tweaks can only fix so many of these things. Plus, his changes to get him balanced have significantly compromised on his design and fantasy (his ult once spawned TWO shadows in development).
