It, along with the Codex, is geared toward giving him more power. If the Doran's Ring or Codex is absent he lacks heavily in power during the laning phase.

With Doran's Ring and Codex, you get approximately 80 AP and 10% CDR (total of 18.75% bonus AS w/ Sorcery) depending on your rune choices. After that, Catalyst the Protector provides health and mana sustain, which improves his already potent bullying potential in lane. Ionian Boots give even more DPS and CDR (30% CDR, 37.5% bonus AS). Then I finish RoA. By then, he already has enough damage and sustain to not need a needlessly early RoA.
