Assuming you want to maximize damage, after you build your core items, 
, what do you build? Objectively the next best choice is 
for the extra mpen. But after that? 
has the highest ap/cost ratio in the game, so that would be the best item to maximize your damage. I'm not trying to make a case for this, I'm just pointing out the absurdity of it. The war on AP has left itemization in ruins.
Inb4 changed to 70 AP and 40% cdr.
i love how ap items keep geting lower ap ammounts but they aren't doing global buffs to champs that have pathetic ap scaling, when a moves have up to 120% ad scaling it's understandable why ad items dont go to 100 ad but alot of ap users have 40-60% scaling aside from alot of ult's that have 100%, you don't usually see alot of 101%+ on ap users
Still would buy these instead of morello, AP isn't everything.
you forgot gunblade as core, it's prob the first item you should get. Also abby scepter gives you defense and pretty much 10% extra damage on your ult.
Um... Yes. it is troll. Kat doesnt need any CDR first of all. Liandrys is also trash on her. Also Ludens is very situational on Kat as well, best not to build it most games. So you are 2/5 on the item build you just listed. Wow. Also with Kats ult the Morello passive is redundant. What is this troll post anyway?
That's not AP itemization being in ruins...that's Morello's being overloaded as shit, which is common knowledge that's simply never addressed by Riot.
AD itemization is too efficient; that's the only reason AP itemization ever feels bad. Mages are as strong as ever, if not stronger. The AP they have doesn't matter if they're still just as capable as they've ever been. Many would even consider them too strong at the moment.
her core includes gunblade, also usually zhonya
anyway i would rather build abyssal over morello
the cdr tho on a single item.
