What if they add widows bite to her kit? (A "What If?" buff)

Widow's bite!

Black WIdow shoots a bullet from her wrist gauntlet which does 25 damage and prevents the target from healing that 25 damage for 1-3 seconds. (Like a venom)

This allows her to get that headshot on a CONDITION and it actually has to be aimed.

They should focus on making her enemies more vulnerable if you guys don't want a rework.
