@Reav3 - Why does Evelynn's Whiplash apply on hit effects?

At current, there are a very rare couple of items that she would be interested in building that add AA on hit effects. Since you've given very logical reasoning for why you're moving her away from AD scaling, a good majority of those items that have on hit AA effects become pretty useless on her. This leaves only that she can really build to utilize this feature, and even then, the Revolver loses it's on hit effect when you finish any item with it, Recurve Bow, Wits End, Bloodrazor, and Nashor's Tooth don't really work well AT ALL on an assassin who needs to be focused on burst and not attack speed, and Lich Bane, while being the only item that flows into a build of hers, is incredibly hard to get mileage out of in regards to the ability. If you guys are not intending to retain any kind of diver build tendencies, can we remove this awkward on-hit addendum to Whiplash and put something else in that will actually benefit her?
