on some champs it will be very strong and help them, no denial,

but e.g.: WotA and rylais are very strong on kennen, morde and vlad,

while the others are medium, so riot would propably nerf the champ,

who benefit a lot from it while the others stay way they are

(same as they did to the mentioned champs)

u pay 2800 gold for 110 ap and 5% cdr (1 large rod and wand give 120 ap but cost only 2560, and 5% cdr cost almost nothing, so the prize should make up for the passive)

and yes riot will someday fill the gap which was created by the removal of starks fervor
