Hey there! You've done an okay job with this guide, however there is A LOT of things to improve on. Such as coding (I've done some in this post ^) Fix your abilities (missed one) and if you are building an AD build, make it AD, not hybrid.

I don't even understand what you are going for honestly..

Vegeta what does the scouter say about these peoples hating levels?
ITS OVER 9000!

You at least need a hextech gunblade for AD & spell vamp. change instead of a bloodthirster and it will be better i think.

um to improve on your guide possible use some images as text alone is really bad.

Also AP Kat is probs better as all your skills scale off AP where as if you build AD shunpo gets no bonus damage.

also try and fix your skill sequence, you didnt take leath lotus at level 16...

AD Katarina works OK with Sorc's Boots, Occult, Frozen Mallet, Sunfire, Thirster and Atma.

What a ****ty item build. Uninstall game dude.

Hmm I guess I will give it a shot, not gonna downvote until I try :)

Build is great!...In theory. The reason Katarina is much more viable as AP is simply one thing; Effectiveness. With so many offensive items contributing armor, AD katarina is gimped by this fact. Looking beyond that, however, is the price for each--AD will always cost more than AP due to autoattacking being a 1:1 ratio on EVERY champ. With AP so much easier to obtain, an AP katarina gains immense damage for a lower price than a skilled AD Katarina. Also, many AP items come with defensive bonuses that just scream "Pick me!"

All-in-all, an AP katarina is cheaper and much more...user-friendly than AD.

HOWEVER, AD katarina's have the advantage of sustained fighting power: Rather than bursting with their shunpo->Lotus->dagger combo, then running around doing nothing while their CD's come back, an AD katarina can chase for the extra 300 damage hits, regaining life and finishing her opponent while waiting for the cooldowns.

Overall, I'd personally prefer an AP build do to it's versatility and survivability, but the effort you placed in actually EXPLAINING the use of each skill (as opposed to showing a tutorial video) is what drives me to give you my +1. Enjoy!

P.S. Pictures, videos, "Glory Pics", and other superficial features would do wonders for this guide.

Misspellings galore, OK build.

Please uninstall ur game and make it better.. U didnt take spell on lvl 3 and build is really bad imo i saw a lot of ppls trying it and they failed hard + they was in my team -.-
