Fizz is boring and linear now
For a long time I thought Fizz needed nerfs. But I didn't think that they would nerf his gameplay to become really boring. People have started playing him bruiser with trinity force now because of how boring it is to rely on your ult to burst someone. His ult looks pretty cool but it's clunky and it's easy to dodge. Also it has a wide radius so you can't exactly thread it between their front line to latch onto the ADC. In comparison it's much easier to land a thresh hook on a priority target.
They put his power into his ult which didn't even characterize the champ. E should be on a higher cooldown and I think making Q a dodgeable spell is a step in the right direction. I agree with the grievous wounds nerf. They just made a champ that just isn't as flexible as Zed. There's no reason to pick him over Zed.
