My only objection to HWM is it tends to force you to use Vestal as a nearly pure healbot because aside from Leper's self heal, the other two characters are helpless in that regard. A few rounds of Jester's buffs brings his actual damage up to respectable levels, though. VES-JES-FLA-LEP is also pretty good, although Flagellant isn't as mobile, suffers when kicked back to third rank by Jester, and is tbh pretty weak against the Sleeper's first phase (Fracture) and the fairly common skellies. I like Ancestor's Pen/Surgical Gloves or other ACC/DMG/CRIT pluses on Leper. I've found VES-JES-HWM-LEP pretty good, too, although I usually set up Riposte on the first round as well as revenge, spam Battle Buff (or Stress Relief or Dirk Stab to move up for a Finale) and alternate between AoE and ST heals and Judgment/Stun with Vestal.
