E also gets blocked by the frontline, and W damage: 250+0.8, nida spear damage: 450+1.2
it may have looked like nida spears, but thats what happens if no enemie builts mr besides the jungler, he prettymuch dealt truedamage to almost anyone.
An locking down Ez is hard, thats why you need some picks that are good in doing so, like Vi Jungle, mao top or nauti bot, all having point n click hard cc that follow through his E, or atleast a tank can zone him away for some time, or a sivir ult to run him down.
Fnatic prettymuch had nothing of that, just that Kalista with janna+lulu+double lifesteal prettymuch becomes a hard to kill bruiser that can easily sustain vs poke, while Azir somehow managed to buy enough time vs EZ for Kallista to burn through the tanks and turn onto EZ in the last fight.
His ult, while beeing strong, looses alot damage per target it passes. If you have a tripple frontline, you backline won't get as much damage, especially if you stay in a minion wave or have pets(elise with max spiders Halfs Ez ult damage...)
you can also reduce the damage of the ult quite a bit with locket.
If people learn how to play against ap-ez, which involves useing your minions as shields, he becomes way harder to use.
Fnatic had some troubls early-mid, but they managed to adapt just in time to turn it around.
You can also hard counter him with Yasuo/Braum, as they both can nullify his ult and also block the rest of his kit.
also, as fnatic has shown, mobillity also helps alot as he is 80% skillshots
