[@Felnarc]

is this a perfect combination for raid party? and why karina is not in the party? like claude - cammie - karina - vinette. what is the reason?

[@Destably]

To be a good raid unit, you need at least one of those:
- A defense decrease
- A lot of buffs (like Win Ling)
- "1,5 party buff" (like Dabin's crit, Ameris' crit multiplier or Vinette's dark atk)
- An elemental decrease and some extra buff (like Toga or Dabin)
Karina only provides damage and nothing else, so she isn't a good raid unit.
