I think she's just making a suggestion to try and remedy something that quite a few people complain about, which is inactive LRs.
Please do not try and tell me that LR activity is good. It's questionable, at best. The blue team deploys senior members into random LRs to try and drive activity, and that's REAL SHIT. So why not try moving the LRs to a more focal area, as it might help boost activity?
