If the 28 Greens on our side split into at least roughly 2 groups, one backing up CRX (which is what people seem to be expecting) and the other addressing the survivors of Guan Zhi's strike (minus Cyan dude), the 100+ yellows and the 6 Greens that lead them...well if I've calculated that correctly (tell me if I'm wrong) then the other group that is not with us is gonna need
help. If backup comes to them from the perimeter group bc the higherups were able to readjust the battle plan to the circumstances, they should be fine. If no backup comes, those ~14 Greens, all G1 or G2 iicr, are gonna be severely outnumbered and overwhelmed. The barbs are quite used to battle, they'll be able to adjust to the surprise attack fairly quickly. They come from a warrior culture and know how to work as a cohesive military unit. Compared to them, our Sect brothers and sisters...don't. They all have unique abilities and the whole force is comprised of volunteers, not people who specifically have trained and fought together before. Never underestimate a well-disciplined enemy unit--even if most of them are Yellows, that many buffed by their Green leaders will be able to at least some considerable damage to G1s and G2s.
Now about your response. The situation with the huge mass of yellows and their Green leaders is something LQ has beaten before and can beat again. She can take out the buffers like she has at the village and when battling the Brute underground with JR. She can also make the whole group less cohesive, prevent them from getting organized, drain their qi and kill or at least injure a large number of them. She's shined in this scenario before. The word around the Sect is that LQ is an extremely powerful combatant, they've probably all heard about what a great military asset she's been so far.
Now I'm not saying that we should be at the rim, handling the Yellows and Green barbs. (It'd be pointless anyway, that vote isn't gonna win.) My point is that if LQ is seen backing up CRX with the Shishigui, no one is gonna argue w that. However, if people see her trying to nab and abscond w the stone, when they all know she could totally help out as a combatant, thats gonna look...bad. Logically, they all should know that grabbing the stone is helpful but when people get whipped in battle and their comrades die...they may look to place blame.
Edit: Whelp, no point in this long post now...my point still stands, I think.
