Would it be justifiable to make it so that ulting to a target afflicted with moonlight does NOT remove moonlight from other targets?
There are other champions that can rapidly dash between minions, like Yasuo and Irelia.
I've always felt like Diana should be able to if she marked all targets with moonlight. Ever since her release it seemed like that should be a natural mechanic.
There's plenty of ways to balance it. You could even go the Kassadin route and increase the mana cost for each time her ult is spammed.
Besides, she's not lacking in the damage department, trading some damage for some more mobility might be fun
