Okay so I just did the vault of glass with a full squad . We were fighting Atheon when I get randomly (so awesome to disable any kind of strategy) teleported to Venus along with 2 teammates . As planned , I take the relic and kill the Vex while they take care of the oracles . However , after using my FistOfHavoc-like attack on the pretorian , he lost health but not all of it . Then I hit him again and he loses his remaining hp . I look away , naively thinking that he is dead BUT NO !! Surprise surprise , sunsinger praetorian is back on his feet with still a few HPs left and a raging desire to punch me in the face . I barely survive his assault and bash him again . He loses his health again and dies again but no sir , Mister Praetorian ain't going down today . You thought you had taken out 80% of Atheon's health ? Well I'm here to screw you up and my praetorian buddies are gonna do the same in your 1200 next attempts . Is anyone experiencing the same problem or am I the only one getting trolled ? Shouldn't Bungie be patching all these little flaws that make the raid such a pain to beat instead of making it completely randomized ?
