I completely agree. I'll have to incorporate that into my guide, thanks for the feedback

Recovery isn't a great Mastery but still better than Enchanted Armor , just a minor annotation. I guess you could add purchase options like Spirit Visage/ Abyssal Mask and Randuin's Omen because they often help you to fit in your role.
You should consider using BBCoding in your guide. Just check out some coding guides and you can make everything looking more appealing to the reader.
