Attention mid laners: STOP BUYING ATHENES
Just had a Xerath who insisted on buying Athenes "for the mana regen", completely ignoring the fact that Xerath has no heals or shield to speak of making the item totally worthless. It gives a pitiful amount of AP, and Abyssal Scepter outshines it in terms of MR.
Athenes is a support item now; STOP BUYING IT ON MID LANERS. Hell, even Lulu/Karma mid have better things to buy than Athenes. What's the point of going Lulu mid if you're not going to build damage? Might as well go support Lulu.
If you want mana, Morellos or Tear are FAR better choices on just about every single AP mid laner. Read the patch notes once in a while so you don't get into game and look like a fool. Unless you're coming off of a 1 year break, you have no excuse to still be buying Athenes on mid laners.
