Rooting has nothing to do with the use of scanners.Even if you sit down, you still can't use VS if you are aggroed. If you are in a fight, you can't use scanners. I always keep my target aggroed, even when out of los. Yes, I am an annoying enemy.
Low hp setup? With enhance health perked I have 6,1k health and I have pretty much best possible equipment for pvp.
Tell me how you can magically summon 4k hp without sacrificing essential parts of traders pvp setup. Id like to hear that also
