First replier - You have a Sapphire versus a Blasting Tome. 400 versus 430 gold. 200 mana versus 20 ability power. Ryze casts something like Q, R, Q, E, Q, W, Q. The Sapphire increases his damage by 16 X 4 + 10. The Blasting Tome increases his damage by 4 X 4 + 12 + 2.1 X 6 (assuming Spell Flux hits 6 times). That's 74 damage for mana versus 40.6 for ability power (and hitting all six Spell Fluxes on champions will happen rarely while minions are there) for 30 gold less. Even if Ryze doesn't hit his Q multiple times at once, it will be his main source of fighting in a lane anyway. It's quite clear that it would be illogical to build ability power on Ryze, aside from perhaps a side effect of building mana and defences on him.
