I could see that armor would help against aggressive early tower dives, auto attacks, and AD ranged if you were duolaning with fizz instead of mid, and the reduced minion damage, but is that better than Magic resist when you mostly do mid against AP?
i would say armor, because honestly, your burst is too fast and you can easily avoid damage with your E in the early game, which is when typically the other ap carry would be doing most of their damage to you. I think armor seals are more effective because later in the game you are a little bit more "tanky" i guess you would say and can take more punishment from the other champs which you cant simply avoid with your E. just my personal opinion though.

Fizz is so good at casually strolling out of ganks, i wouldn't take armor yellows for that reason alone. I typically run flat mana regen yellows, since his harass costs a lot of mana. But that's because I only have one AP rune page more than because I believe it's the best choice for him.
