"Xerath is one of the few mages actually hurting his damage but getting mpen, since it lowers his damage from voidstaff, 15% mastery and W."

Bull. Shit. It cannot HURT his damage output, it just means the % magic penetration is going to affect a lower MR. Thinking the way you do, Xerath should actually avoid building Void Staff since his W mpen decreases the benefit per gold he gains from it. But no, he shouldn't avoid it, because in the end it's still an increase for his damage output.
