Rushing RoA: I would go sapphire->boots (if necessary)->finish catalyst->sorc boots if you want or if enemy bought mresist->finish RoA

Rushing AA: If you're going to get AA, you need to get tear early, which means delaying or skipping RoA completely but you will get a headstart on farming the 1k mana. I would get WotA after either tear or boot1 for survivability if you choose that path. You can go tele+revive and build him glass cannon (swap RoA for WotA) since he'll do enough AoE damage worth his life, then revive+teleport back into the fight to finish off survivors and ult.
