Here's a thought on Diana: Reduce damage on Lunar Rush if the target isn't affected by Moonlight
Riot dislikes the following Diana combo: R->Q/W->E, because it's impossible to dodge.
Here's a solution: If Diana dashes to a target and it isn't affected by Moonlight, Lunar Rush does less damage (and doesn't refresh). If the target IS affected by Moonlight, the cooldown refreshes and Lunar Rush deals extra damage.
Good or bad change?
