Guide lacks imagery just a long wall of text, most people will skip over your guide and just find a different one(being honest), several sections missing in this guide(ex:Summary, changelog, Combat Techniques, pros/cons) and your build needs some work, as he needs some survivability!

Try including a section explaining what AP, AD, AS mean, not everyone knows what those stand for(newbies).

Try jhoijhoi's guide called "Making a Guide". Hope this helps!

the build is decent, but it lacks one very major aspect. SURVIVABILITY there are so many ways that you can get survivabilty with fizz and this build doesnt use any of it. i would substitute morello's evil tome with a rod of ages as it gives hp good, scaling ap and mana (which fizz has problems with especially early game) this build is incredibly squishy so the least you could get is a raleys crystal scepter. you may be able to kill some backdoors but you will become useless in a teamfight because you'll die in about 5 seconds. especially because fizz is melee
