Change/Nerf to Fizz ult?

I think that Fizz's kit is overloaded at the moment, especially due to his ult. Alot of the popular mid laners this patch include the immobile mages, ex. Syndra, Lux, Viktor, Annie, Velkoz, etc. As a player of these mages, I find that Fizz's ult is very very very hard to counter due to the lack of a movement skill. His ultimate latches onto you so easily, and along with the 1300 range, it feels impossible to dodge. It just clings right on to you and you can't do anything about it. Fizz's damage does not rely on his ultimate, so I do not understand why it is so strong.I myself have around 10% win rate on games laning against Fizz, and I thought I'd try to put this out to Riot.

So say you are playing Annie and you are currently level 6. You should have, (idk really im just guess estimating) maybe around 830-900 health points, given that you have (in some cases, you would have an abyssal scepter, but count that out for now).

Fizz ulties for 300 (+120%) magic damage. So if Fizz's current AP at level 6 was around 180, your HP as Annie would be reduced by around 65%.** BY ONE ABILITY. **

Just thought I'd address this. I would like to see a change to Fizz's ult. Here is my thoughts for change. I think that the hitbox radius should be greatly reduced, and damage% reduced to around 100/175/250 (+50% Ability Power) to 300/375/450 (+70% Ability Power). It is very easy to be tower dived by a level6 fizz as an immobile mage, and I'm tired of it. feel free to leave Thoughts and opinions :)
