Reduced Spell vamp on multi-target or AOE spells would prevent this from being viable, at least in a "rush spellvamp" to heal off your ult solely kind of way. Also, considering his crazy damage simply rushing damage should allow you to deal enough damage to wipe out a team rather than gambling with you staying alive longer. That being said, Zhonyas is a great item on him and spellvamp definitely doesnt hurt in laning and long fights.
