That's bull crap. I was doing the lost sector without knowing about the throttle and I was receiving tokens, 3 to 5 tokens. I was hitting 2 sector per area than go to a new area via fast travel and did those and still got all of the tokens. But I think strikes gives me more tokens and they are more fun. Here's a fun fact stop complaining. Do 2 sectors than hit either a strike or crucible than to back to hitting 2 sectors and repeat.
