I don't get it.
Edit: I feel that this guy has a survived a Golden Gun shot from me. I do not have the recording of my POV, but I'm 100% sure that I hit him. I think we should have traded kills. He survived a Thorn shot from our teammate. You can see the green burn on him when he pops back around the corner. He then survives two Gjallarhorn rockets from my friend (the POV of the video).
Edit: Some people are saying he slid under the rocket, but two were fired. I assume people are talking about the second one. The first one does 37(?!?!) damage and the second one brings up 'Immune', which I have not seen in PvP before, and then does 25 damage. How do you slide under a proximity based rocket? He should have died in the explosion.
