Well, if u want to hear my opinion on this, then here it is. The second effect some large anti-pattern built in it when compare to it's first part of effect.
 * Conflicted Purpose
 * This makes players queasy about using the ability much like in the optimization case, but it's a slightly different problem. If the ability exists for too many different purposes on an explicit basis, it becomes confusing. this is different from something like blink which can be used for many purposes, but has a clear basic purpose.
 * Unclear Optimization
 * When players KNOW they've used a spell optimally, they feel really good. An example is disintegrate on Annie. When you kill a target and get the mana back, you know that you used it optimally, and this makes the game more fun. On the other hand, some mechanics are so convoluted, or have so many contrary effects, that it is not possible to 'off the cuff' analyze if you played optimally, so you tend not to be satisfied.

So yeah... it will be hard to balance it, and yes, the Ad reduction is anti-fun. If anything, I will like to prevent taking away anything if possible and the duration is too long in my liking. I had questions for 8 seconds, but increasing it even more or adding a last second invulnerably is too much for me. Also, I the cooldown will need to increase after your buff for sure, which I really don't want to do.

Also, I think the current Kayle kit has enough reason to go build AD without the need to add AD scaling.
