You balance it through increasing/decreasing the window for shield penetration, the amount of shield penetration, and the cooldown of the active. Edge of Night would be broken too if it gave you a permanent Banshee's Veil. I don't see how this is any different. Active items give you windows of being overpowered. That's not an excuse to condemn all actives. What if Youmou's gave you +100% speed for 5 minutes? Everything is broken by that logic.
Increasing/decreasing the window for shield penetration? There already is that window of time...by waiting out the shield...shield is temporary health...and your comparison doesn't...what even...
It's like you're making it seem as if you believe that shields are permanent, otherwise why would you compare it to making other stuff permanent?
If you're arguing that making something permanent would be broken "by that logic" then why are you complaining about shields? They're in no way permanent...
And if you're gonna argue about the shields being "permanent" relative to the window of time you have to assassinate them, then you gotta pick your fights better...
