Fizz is def not an assassin anymore, a bruiser yes, but not assassin
There is at no point in the game where he feels like an assassin, a 2 second delay on all damage on a melee only champion. There is no burst, mages burst faster, adcs kill you faster, other assassins kill you faster, other bruisers kill you in the same time. The update is almost a nerf across the board with a few small buffs which don't come close to compensating. The numbers/math isn't there and the gameplay isn't there, he isn't an assassin anymore. How can one be an assassin, have very limited tools to survive and expect to last in melee for a full 2 seconds to get any damage off. It just doesn't happen. His mobility "hardest to kite/peel in class" is far from that, being at best average in class due to no resets, mediocre gap close range with each ability and forcing to use to do any damage as he has no range besides ult. He's actually one of the easiest to peel.
There is barely any AP itemization there to support living extended periods in melee besides zhonyas which is actually COUNTERPRODUCTIVE to what fizz needs to achieve as if he uses it, he will have to restart the W dot. Bad early lane so can't get to decent mid and horrible late as any champion kills you faster as they aren't gated by internal CDS on their own kit. I can't wait for the numbers to pop out and show horrible win rates across the board. There is no feeling of usefulness unless you want to target the enemy tank. All the enemy damage dealers kill you faster than you can "wait two seconds until you have any damage". And they can easily just kite away from the W charge, as if the rest of his kit didn't have enough counterplay. Q can be dodged, E can be dodged, R has so much counterplay they could nerf the cd to 30 seconds base and would barely change a thing and now wait two seconds until you can get a measly 1.0 ratio when the old W did more over that same time frame. Very bad rework and looking forward to some big buffs.
