depends on the situation and the champ u play, e.g.:

i play J4, due to his low ap ratios kage is no option, so i get philo+hog+avarice, upgrating hog and avarice and selling philo later,

but if i play blitz, who has a total AP-ratio of 2.0+1.0 from lichbane (yes i go lategame for tankyness+AP), i go forphilo+hog+kage
