While technically not confirmed as of the encryption of data (And the ensuing bugs, thanks asobism) from the update that created her, it is incredibly safe to assume that Meiling follows the standard formula for 3x hit attackers, as asobism does not tend to variate deviate from standards with these.
As an active, Meiling's only uniqueness is that she will debuff the enemy's agility by 3 if she breaks a defense they have. However, the damage comes off her solid attack stat, meaning she can serve well as a source of damage in colosseum or as a starting player. She will also REMOVE defenses, meaning if you have a pesky boss spamming defenses, she can help there in PVE.
