F2P, but I might have to whale a little to get both Caesar and Burnice.

Soldier 11 is the DPS you need for the team. Ben and Koleda are a little redundant, since they both operate in the role of building daze rapidly. You can use both and run chain attacks more often, or replace one of them with Lucy if you have her (or anyone else that might boost attack or cause debuffs or generate anomaly for Disorder procs).
