Hela really shouldn’t get to survive after her health is depleted in the middle of her ult.
Hela’s ult is one of the best in the game there’s really no getting around it. Though in the rare chance that you and your team focus fire on Hala and get rid of her health (which is increased to 1000 in this state) she isn’t eliminated. She still gets to live. This is the only ult in the game that’s like this (unless you count Monster Hulk) and given that her ult has so many upsides this shouldn’t be the case.
I have no idea how this survived her Nerf but yeah, here we are.
