Ok... This build has not been updated for a while, i'll do it when i have time. If people want to counter you with MR, get void staff which is even better with resistance modifications.
As for your question, it has no sense... How can their team counter fizz by being "too squishy"... Usually as fizz, you want to one shoot one of their carries to make a TF 4v5... Usually even without a void staff you will manage to do that... If they get GA, kick the guy you just one shot's *** when he comes back, if you have a decent team you should be able to kill him another time.

These are items fizz can get, but what if they start countering him with items, or thier team is too squishy to finish off, you have no situational items, or explanations of what to do if that occurs

The problem is i just joinef this website and i dont know how to put colour to text ;) i'll find out when i have a bit more time. And i dont know either how to put the mastery page thing at the beginning of section...
I'll try to find out! Well i'm glad it helped some of you i'll do my best to relook it a bit;) i even found a few more pros and cons!

I'd like to vote up on this guide, because it is great! However, I feel that some of your chapters should be a little more in depth and as the others had already said, a little more colour would do wonders for this guide.

Chapters that could be expanded could be your rune page. You said standard runes, however why do you prefer them over other runes?

I love your Rabadon's Deathcap maths vs Lich Bane. In fact just for that section I think I've reconsidered my own build orders for when playing Casters :D

When you update your guide I'll definitely reconsider holding off my vote :D

Rune Planner
Mastery Calculator
Item
Like Crazy said add some more color especially to your Pros and cons section.

Really nice looking guide you got here. All that I recommend is that you put some more color into your chapters when you write. Just to make the long paragraphs look a little more interesting.

Good luck!

Thanks ;)

Its good build i love fizz too i hope i will be good with :3
