thanks for the reply did a little more reasarch and yes you are corrrect i could not find a perk or utility thats gives guardians stealth.However that does not change what happened to me and others i have been in discussions with other players who have had the same thing happen to them. I know Lag when i see it i also have a program that time stamps it for me when it happens It was not LAG .Nor did anybody fast travel or warp in with any kind of invite because i was already engaged with the enemy .Was just trying to figure out how they were doing it.
