I like this guide, but you can do it better! Add am item section, pur the pro and contro at beginning and add something about combos :)

Add more information, and your Pros and Cons section should be the first section below your introduction because it gives you a brief thought about who this champion is and how you can play her most effectively

Guide lacks a bit of content. You should talk about items and maybe more about Gameplay in your guideitself. Furthermore, I really like your cheat sheet but I guess that Rod of Ages is maybe a possibilty but does not fit in your Example Build because it's an early game purchase.

Greater Mark of Hybrid Penetration would seem like a better option on Diana in my opinion.
