Compare to ap item, there's only 2 items you can build from needlessly large rod, deathcap is expensive and hourglass is situational, so Void Staff is the useful item for them, since there's no item that can reduce enemy MR when you use skill(malady work when you attack), and abyssal staff cost almost the same as Void Staff give only 20 reduce MR.

So that's why this item is not popular as Void Staff
