That's why you need to time it correctly :)

That's a pretty big "if", especially if you're up against champions like Fiddlesticks, Shen, Alistar, Blitzcrank etc. Maybe you should cover that in your advanced guide :p

Thank you very much. Yea, once she is fed, she can easily kill champions if her ultimate is not stopped.

I wish you luck and a lot of fun playing Katarina! She used to be my girlfriend's main and from what I've seen, once Katarina is fed, she is basically unstoppable.

I will be updating this guide for more advanced players too once I learn more about the champion.
I will have a Beginners one and a more Advanced one hopefully.
And thanks for the tip, I'll enable that now :)

Also, friendly tip: you DO want to turn on the "Forced Comments" option on your guide to protect yourselves from trollvoters who will instantdownvote.

I agree on your last paragraph, and it certainly answers the questions I've asked as well. Upvote earned!

Another question though: will you keep focusing this guide for beginners only, or will you also direct it to more advanced players in the future?

Thank you for the comment.
To answers your questions.

1. I've been using HEAL ever since I started playing League of Legends and it has saved my life a bunch of times. I know its not the best choice, but for beginners its really good + you can help your teammates too. Saved a couple of my teammates lifes with the heal.

2. I went for Haunting Guise because it doesn't cost much for early game and it helps you out because you can kill your enemy faster. I forgot to mention that once you reach Void Staff and have it, you can sell the Haunting Guise after and buy the Zhonya's Hourglass faster.

I've been doing this build for quite a bit now, and I've been getting a bunch of kills and carrying my team all the time. I know this build is not THE BEST out there, but I think its good to begin with. I usually get a about 3-5 kills by the time its mid game at 10:00 so that allows me to buy these items way more quickly and be stronger to pick up kills easily.

This guide has both positive and negative points, so I'm not casting my vote yet, but instead am asking you some questions:

1- I know it's a beginner's guide, but why bother taking Heal since it falls off greatly lategame?
2- What is the point of building Haunting Guise if you don't turn it into Liandry's Torment later? I think other AP items are better for Katarina, for instance Rylai's Crystal Scepter which allows her to chase more easily or Deathfire's Grasp which gives a huge amount of AP and 15% CDR
