Kayle autos that are empowered by E don't crit. To be clear, I'm not talking about the bonus damage from E: the physical damage to the primary target doesn't crit.
This makes for situations where E-empowered autos deal less damage than regular autos (if you crit), which I think is undesirable. I'm assuming this isn't intended but I could be wrong.
Also, damage from fire waves crits separately from the main auto. This could well be intended, but my perception was that Riot moved away from this kind of interaction with some other champs.
Lastly, I love new Kayle. Good job!
