As a some who mostly play support. Hearing “fire in the hole” is practically a death sentence because 90% the time my team won’t be able to killed it. I have killed tires by myself when playing zen, but those are far in between when I’m lucky and correctly predict where the tire will jump out of. Or when the junk is stupid enough to have the tire run at me in the open.
Pretty much the only thing I do when I hear junk’s ult now is to hide/separate myself from anyone else on the team so I would be the only one to die.
