Self rez is a super so it doesnt apply but thats why it should receive more self rez shield since they get a 1 shot melee if its charged before death. To survive a self rez snipe you need solor armor chest plate, ram and max armor and even with that you only have about 25 health whichh can easily be countered by spraying the body shot or switching to a primary if you keep your distance from the guardian. This makes it so you dont need that armor and stats and if you get headshoted as a self rez in animation you only lose your 75% of sheild which is helpful since they have super armor and will be out of animation right when the get shot. Maybe my percentage for self rez animation armor is wrong and should be increased if it is not correct. This should help the rez snipe theory be true.
