Well it is because hack doesn’t disable primary fire, which is where Baguette gets her heals from.
Unless she can still use E, I guess not, never noticed.
Rein’s got something better than hog. Armour. Armour cuts in half whatever hit of damage lower than 10 and above 10 it cuts 5 hp from it. Reaper’s attacks are pallets which do less that 10 damage each. Reaper’s max damage hit is 280 with a full pallet headshot, rein and orisa make it 140 and a body shot 70.
