Thank you for the feedback, I will continue to work on this guide while trying to keep this in mind. Right now I am just starting to work on this guide, so there will definitely be improvements to come in the future.

This build feel very basic, try to add some BB-coding to make it a little more readable.
In it's current shape it's pretty ugly. The information is correct in most cases, but you should really read into what runes you use and why, also add some alternatives (just upload screenshots with runepages and mastery-pages). Add your items in order and not just throw them in together. Also you must add a chapter about how you play Sivir.
