I use that all the time outside of nightfalls and when I'm doing raids legit, my point is that just cause someone uses rez it doesn't mean they can't still be aggressive with their super in the right situations, I also don't ever run rez if someone else in the group is but having one self rez is pretty helpful especially in nightfall if you don't want to get kicked to orbit but I agree many people mis use and overuse the rez, comes down to the player not the perk itself
