Some small things I have for this guide. You should consider Ravenous Hunter as an option to take instead of Eyeball Collection or Taste of Blood because you can actually heal off the damage from Blade of the Ruined King, Guinsoo's Rageblade, Stormrazor, and Second Skin. You should also consider taking Sorcery with Celerity/ Transcendence and Gathering Storm as possibilities instead of Domination, since Kai'Sa is a good scaling ADC.

Hey mate! The guide is not bad, keep up the good work! If you go Stormrazor and Bork on Kai'Sa I would take celerity, since you get much more extra stats from it. Some people say its bad on Kai'Sa, but I dont think so, because you have much better synergy with some supports and movement speed buffs from items or drakes etc.

This actually really helped me! Keep up the good work!

Decent guide, but I feel like some visuals would greatly improve its readability. Using bracketed icons for specific items, champs, or abilities provides a useful icon for the selected item or other, ex: Kai'Sa. In addition, adding pictures and/or videos for abilities, runes, etc would be really nice. The use of line breaks in-between big chunks of information is also a great way to help people find the info they're looking for quickly.

More matchups including support champions, and possibly some good synergy picks would be a huge help as well.
