I'm sorry but this is wrong
Lux R receives a cooldown of up to 50% if she kills her target
no Riot you've gone too far Lux with 40% cdr has a approximately 30 second cooldown on her ult half of that is 15 seconds
that's URF cooldown what is your problem Lux is my highest ranking champion, I've never ever, no matter how hard I was crushed, found her weak in any way imaginable she's actually very strong so why don't you please, just revert this buff entirely
who doesn't go all-or-nothing due to most of the damage being on ulti. This buff feels like the Cho'Gath one where it won't push her into the meta but will just create another issue for lower elo.
