Can we get some insight on the reasons you had to make the Infernal Drake's buff a % increase in Attack Damage and Ability Power? Right now, it benefits primarily autoattackers and champions with good offensive scaling.
Do you think the fuzziness of the buff (as it is effective against structures, minions and monsters rather than just for teamfighting) is in an acceptable level?
Were clarity concerns present around the fact that a +% damage against champions buff would be less visible, while AD/AP are displayed openly?
Did you think that affecting base damages on skills could have lead to less healthy gameplay?
Maybe there were balance concerns around champions that get damage from defensive stats, or a desire to make the buff attractive to champions with AP-based utility scaling?
