Ok, so I was running around punching things to death. And I noticed a few players I had a hard time killing. I would punch them three times and they'd take no damage. Then about ten seconds to a minute later, they'd suddenly die to my fist. Like I'd have respawned and be seeing them again, pull out my pistol to shoot them and watch them spontaneously die to the fist attack I had used like a minute ago. Oddly, it seems to only affect people that should have died to melee. Another time, I hit someone 3 times, they should have died, but they took no damage. They immediately threw up a shield and on my kill screen, a few seconds in, I saw them suddenly take a bunch of damage-and lived because of their shield. (They took the damage from my punches then). Another time, I went striker and used shoulder dash on someone. They lived with no damage and shot me with me shooting at them. Several other players shot at them and they took no damage while they murdered my allies for about 10 seconds before finally dying to my attack. This was the same group of players for the most part in a series of crucible runs. One thing I noted was that they did seem to notice me attacking them since I'd sneak up on them aimed in and then start punching them from behind and after the first punch or so, they'd turn around and either: pull out a shotgun and shoot me (why did they think they had time to do that and why were they invincible long enough to do that?), or proceeded to punch me back or just shot me. It wasn't just one group of players or one specific players, but it was usually only a few players on a team. So I'm going to call this a glitch since I doubt it was intended. === Update: experienced some of these people again. Tried to shoot them this time. Same thing happened with them taking my hits up to a point, then suddenly I noticed that there was an odd sound as if I was shooting at an object instead of a player. I pulled out my fist and punched them a few times. They seemed to notice my punching them and turn around and shoot me a bit until I'm almost dead and suddenly... they die to my weapon... That I had fired like 20 seconds ago. Another player (was tbagging me after each kill and was teleporting everywhere (not blink, titans don't have blink) and sometimes would die before I respawned, sometimes after I respawned, and sometimes just wouldn't die).. I shot him, my team shot him. He managed to kill 4 of us before my fusion rifle damage finally kicked in and killed him. Fun part? I think he knew because he didn't even try to find cover. He just walked up to us and started shooting as if he knew we couldn't kill him. I reported him for bad connection. So I'm guessing this is something people are doing on purpose based on the behaviors of some of these players..
