RoA on vladimir?!
just giving a look at all the item I end up wondering how RoA was cost efficient for vladimir... I tried once building 4 RoA and a Deathcap just for fun and the result was pretty sick... no CDR tho.
still 500Health=+12.5AP 100AP=+140Health with deathcap giving 162AP=226.8 health increasing RoA by 49health and 39.375AP
so in the end RoA give 689health and 151.875AP it's far more than Rylai's, Lyandri's, Hextech belt, or Luden's; and just for 2700 gold.
then as for comparing the 25% healing gain from the 15% of the hextech gunblade... Q heal for 25% of base damage value and 60% of AP scaling damage ratio. So hextech gunblade increase by +60% healing from the flat value compared to the healing. and increase the AP increase of healing by 9%, while Spirit Visage increase AP healing by 0.875%.
Just wondering how gold efficient would be to go... deathcap, RoA, Abyssal, gunblade, Spirit Visage, Lucidity boots?
... which gives only health (and a very small amount of AP due to his passive).
