Yes it does.
Shark can be removed by QSS or Zhonyas, and if the shark does not hit, you lose over 600 base damage and 1.4*AP ratio in your kit, making you the most underpowered assassin.
For reference, Zed's base damage is over 1000 as long as he autoattacks once in his combo (without double shuriken). Talon's base damage is among the highest in the assassin block for minimum effort, with 1200 base damage. For Fizz, his base damage WITH LICHBANE sits at around 1120, which is only average for assassins. But if he does not have a 20% damage bonus on his ult, his base damage falls to 800 - way too low for an assassin.
Additionally, Riot made it so that Q is worthless to rank, while you cannot trade with any AD mid because you cannot spam E for damage (you run OOM faster than they run out of health) and you also cannot trade with them using W because they have stronger autoattacks and they still have actual spell damage available to them. Fizz wasn't a good mid against AD mids, now he doesn't have any presence in a vs. AD assassin lane.
