With CDR from rocket belt/abyssal/Hourglass and Ionian's, you'll have your spells up so much sonner, plus the extra Mpen from Abyssal lategame and the dmg active from Rocket belt bridge the gap very well, so the AP loss won't matter all that much. Also his ult is devastating right now and with 40% CDR, you'll have it up every 70 seconds or so.
