User blog comment:TheTobarMethod/My Fix for AP Ez/@comment-4652200-20130324184607/@comment-81.237.243.81-20130324195031

the first example would be a "bad" implementation as it would amplify AD ez since his allies can use the reduction. There is no easy way to improve AP ezreal without affecting AD ezreal, unless you make the player specify what kind of ezreal they are building and change the abilities according to that (think giving Ezreal a evolution (ala Kha'zix) point at level 1 that either makes him a AD carry or AP carry).
