Big Problem With Fizz

I just played a game where I was Lux versus a Fizz. we both started dark seal and within ten minutes I was already 3/0 versus him with neither of the junglers assisting. I did amazing versus him, outfarmed him, and even dealt more damage at the end of the game. But there is one thing stupid with Fizz.

Every assassin's purpose is to have a semi strong early game, and be compensated with an amazing mid game that can snowball into easy wins if played correctly. But Fizz is on a different level. With no stacks on his dark seal and sheen, if he lands his ultimate on you, you are dead unless you are a tank (and maybe not even then early game) or you have a spellshield like Banshee's Veil or an ability like Nocturne's W. You can't land cc on him unless it's instant point and click because he can use his E to get out of any situation. It's stupid. and he can use Q to go behind you instead of in front of you. He killed me when I was full HP and full mana, I was under turret, and I had both my w and my barrier up. I used them both and still died within 4 seconds. In what world is that balanced?

Now, I wouldn't make a post about how "X is overpowered" If it was just one instance. Champions like Fizz and Talon made me stop playing mid lane entirely, and I am now a Jungle main with Mid as my secondary. This is every instance I fight a Fizz. And while, yes, I am in high silver elo, and you could easily say "Well you're in silver, you just need to get better at the game" I have went on multiple low level smurfs, my old bronze account pre-ban, and on my main account that is now sitting at Silver I. Every fizz can and will do this under turret. The only counter is Zhonya's Hourglass or Stopwatch. But Stopwatch only helps once, and Hourglass doesn't help because of how low of ap it gives, and how it gives 45 armor when Fizz is AP. And I'm not about to rush Hourglass before Luden's Echo. I shouldn't have to change my itemization that much just so I don't die under turret.

PS: and while I usually can dodge his ultimate, not dodging one ability lv 6 shouldn't result in me dying then and there without the chance of counterplay.

TL:DR, nerf fizz's early game damage outputs for his ultimate and E or W.
