Hi! First of all, thanks for the feedback!

About morello's tome i take this as last item only, and mainly because you don't always have blue buff and it also allows other teammates to get the blue buff. I understand your point but this works for me. good AP good cooldown reduction, i like it for end game, in most situations.

About the hextech i know lots of people like it and it is indeed good for the spell vamp extra survivability, but i find it i'm doing great in small fights without and i try to always come after full group fights have started so the opponents already have a primary, therefore i dont find it necesesary.

About your runes i agree i should change and look more into them !

Havent got more time right now to answer more, i will get back tommorow for more answers and comments.

I think you didn't give enough thought to your guide.

You propose items like Morello's Evil Tome for cooldowns, but even though it gives you 20% CDR and 75 AP you waste money for effect you wont use 12 mp regen/5 sec. Second bad thing is that you also use Ionian Boots of Lucidity which gives you 15% CDR and with Elixir of Brilliance, Blue Golem buff you already have maximum 40% CDR, so Morello's Evil Tome 20% effect is totaly wasted and it shows that you payed 2350 Gold for 75 AP and in that place you could buy another Needlessly Large Rod for 1600 Gold and have 5 more AP. At that you still have Voracity which basickly neglates your cooldowns after kill/assist (except for Death Lotus).

Another item Lich Bane I think is no good, but that one is propably to prefference of player. I'm not hitting with Katarina too much from hand (mostly for farm). Her cooldowns are ridicoulusly low (lvl 5 Shunpo on 40% CDR has about 4,5 sec CD if not less) and as I said before Voracity neglates CD after every kill/assist. With that in mind you will deal more dmg from simple skill spam rather than hitting enmies. Additionally Lich Bane gives you 350 mp which is wasted on Katarina because has no mana the only item i consider good even though we waste mana bonus is Banshee's Veil which will help you to cast ulti without distruption (at least for 1 skill every 45 sec)

And the last thing I would like to add about items is then you are not even mentioning items that greatly increases survivality of Katarina i mean of course Hextech Revolver it gives you AP as well as spellvamp for only 1200. Later you can upgrade it to Hextech Gunblade for additional dmg to Death Lotus from AP as well as AD.

About your runes:
Greater Seal of Cooldown Reduction for real? it gives you whole 2,61% CDR which is wasted anyway if you have Ionian Boots of Lucidity, Elixir of Brilliance and Blue Golem buff.


Hit and run is only a strategy used to take less dmg but if you dont want to be so squishy then change those seals for:
Greater Seal of Armor or Greater Seal of Vitality
They will help you to be more aggresive.

Greater Glyph of Ability Power those runes are not so bad but it's a minor mistake. Because Katarina deals most of her dmg from her Death Lotus (which is 70-80% of total dmg you deal to enemy champions) its a better idea to use Greater Glyph of Scaling Ability Power
Little math:
0,99 / 0,17 per lvl =~5,82 AP
meaning on lvl 6 Greater Glyph of Scaling Ability Power gives more AP than Greater Glyph of Ability Power.

And the last thing your guide is just wall of text, try to use some BBcode like = Katarina
