And widow maker can do 300 damage headshots every second and change.
In reality however- she doesn’t.
Just like in reality, mercy isn’t going around doing 1-200 DPS on a consistent basis.
Brigitte however, DOES regularly do damage.
Where as mercy is routinely limited to employing her beams- Brigitte is required to go and smack things around.
She may be “close” range, but the actual range of her mace and the sweep it makes are pretty decent- and let’s be honest, has very little aim demand.
And while she can’t crit with her mace, it does through multiple enemies doing full damage to all of them, while also going through shields.
Add in the damage from bash and her boop- Brigitte actually has some fairly consistent burst damage at her disposal that she’ll be routinely available to use.
In practicality- Briggs is securing many, MANY more eliminations than mercy ever has (many multiples over what mercy gets)
The question wasn’t if mercy “can”, it was if she does.
To that the answer is, an overpowering- no.
Brig can definitely counter and disrupt Doomfist quite well- being able to stun him quite easily on his engages and in close quarters combat. Timed right she can boop him off course or stun his escape- and she can readily save people he’s attacking reactively or pre emptively.
However that said- while I’m against Brigitte being buffed
I’m also against her being nerfed at all.
I’d leave her alone, personally.
