Bro doesn’t understand how a 67% CD nerf on a hero who has to use their movement skill to keep up with allies to stay in their 15m beam range feels very noticeably bad 
Especially when the entirety of her kit synnergies got thrown out of wack by said change. Her beam linger out of LoS/Range timer, her rez timer, etc. all were built around 1.5 second GA, nerfing it to 2.5+ heavily threw her kit out of wack, which the Devs adknowledged.
