_Lux is great at picking off enemy champions, thanks in no small part to Final Spark. However, the **high cooldowns** on her kit mean that even when she's sniped a priority target, Lux is left without enough tools to reliably convert that pick-off into a greater advantage. This can lead to scenarios where Lux stalls out a game without the firepower to actually close it out. When Lux really nails her fights, she'll be rewarded with a faster recharge on her most threatening tool so she and her team can more immediately press the lead._
Lux has 27 seconds of cooldown with max cooldown, do you really think she needs this kind of buff? She already dominates early, mid and late game.
I love Lux, but this will just make her completely busted.
