Even in PvP. Being unable to kill a striker is just ridiculous.

You instakill all enemies regardless of if they are in their super so long as they are close enough to be in that aftershock-radius that you leave behind after impacting with a surface or your target. The only way to survive with striker is if you manage to escape the initial blast radius with a shoulder charge, or if the game bugs out. I’ve yet to personally test whether you can survive with Eternal Warrior equipped, but I’d have to imagine probably not.
