>but other than this single mission I don't think you ever really need such mobility.
Eventually they are going to release biweekly PVA missions with Frenzy modifiers like the current Drills. Mobility dolls and Vanguards will be useful on those missions.

Zhaohui also isn't bad for buffing Tololo's Lightspike passive and for an aoe doll she has decent single target with her 2x support attacks + whichever skill you use on her that turn. 3 support attacks at V1 also.
