I prefer ArPen, because it helps you harrass (which is the main job in your laning phase) and it scales better into lategame, im too lazy to do the maths but i think its more effective against champs than flat AD (some might argue flad ad help lasthitting but, "hey, you're support, who cares about lasthitting?^^")

i prefer frozen heart for the CDR/mana (and more dmg through manamune)but i see randuins has a good synergy with his ult, lets say you ult into their team (what is most likely to be happening) activate randuins and you've got a "soft" amu ult
