If your going to nerf his Q, give him some love.
Probably my third time making a discussion about new Fizz, my main problem is that you nerfed his Q so hard that at 500+ AP and 5 items it does no damage. I understand you want him to rely on ult more than Q but making his Q this weak makes Fizz so much less fun to play. As I played a few games with Fizz, I noticed that mainly he just simply does a lot less damage. When I play Fizz mid, I try to get a first blood at level 2-4. Having my Q do decent damage was a big part of that. While his W is still fine as it is on for quite a while and the grievous wounds made no sense (I still would like them applied to jungle monsters, maybe only if you have smite :) ),but his Q does so little damage before Lich Bane and 3-5 AP items that it is now more useless than his W. Generally now I wait until level 6 and ult instantly and kill them, but since he is very tough to lane as since all ranged champs can just poke him with ease, you could at least give him even temporary buffs for his pre-six stages. I've seen even with new Fizz that he is only good if he gets fed early and his ult allows such, so you may want to consider nerfing his ult bonus damage if you choose to buff another one of his abilities as his ult is now overpowered for him doing low damage.
:(
,also:
unlike what you said,
all champs who can get first blood easily without ult. And a lot of them do still have major affects on teamfights. Nidalee doesnt even have a legit ult anyway.
