I'm going to advocate for the offense, for a few different reasons.
- First, we're an area buff/debuff specialist. The core attack is going ot be the one with the highest concentration of both friends and foes, and thus the place where our "everyone we hate is constantly attacked" and "everyone we like gets little buffs" themes get exploited to their fullest.
- Second, Zhengui-as-turret is weak. It's a secondary role for him at best, and among a scattering group it's even weaker, because he's unliekly to be able to leverage his area effect. Going direct assault is our only real remaining chance of letting Zhengui contribute to this fight at any level above "anemic" - it's the best place to catch them ont eh ground, ti's the best chance to hit them somewhere they wont' want to run, it's the best chance to do things like layer an Ashfield Flowering or two across absolutely everyone... and so forth.
- Third, Cai Renxiang is a shock-and-awe specialist, with a few area buff/debuffs of her own. Her place is at the vanguard in this one, and our place is at her back.
- Finally, if and when The Surprise comes, it will come here, at the greatest concentration of forces, where it can best preserve the lives of the Cloud Tribe and best damage the sect forces. If we want a chance to disrupt that attempt (by whatever means) then the core of the fighting is where we need to be.
Of course, there's also the benefit for both Sect Points and rep. In addition to being in the best position to show off, and the best position to do something decisive, we're also in the best position to have basically everyone enjoy that little edge that comes with being Ling Qi's friend in fights like this... and little blessings like that can rack up some nice social benefits, when spread across the group.
