You could get to that kdr, then just use life taker in quarantine to level up to like lt or csm in a day or so
Did you read the topic? The dude posted the thing saying how his kdr was high. He never played quarantine (which in the first place does not raise your kdr) and that renders the post "its called lifetaker in quarantine.... " completely pointless and not helpful at all. Lifetaker in quarantine has nothing to do with this topic.
