Good point, Ive been seeing more and more eye of equinox because of that exact reason. Feel free to build that, I'm not trying to control your build but open different pathways to build it, you can not always build the same thing, some teams have more AP or AD than other. Censer would another great thing because of the heals bonus if taking bond of stone, It also allows you for some more movement speed to possibly go mercury treads and ninja tabi's.

so i like the guide but why not get eye of the equinox you save space by not needing sightstone. Also I like ardent censer for making the heals do more and the bonus movement speed. Plus it gives mana regen ap and 10% CDR.
