Designed by my guildleader Scorn who also comments here. We have shared this with our entire guild, so I hope he doesn't mind my sharing with you all to try it out:

X Calvin (morale between 50-75) Cianna (100 morale)
X X Main (100 Morale)
Blood/biggest hitter(100 Morale) Shayd X
The morale is important as you all know for the timing on Calvin's Willbreaker. In this formation Cianna stuns (usually) on first hit, then all have round of hits, main dies (unless shayd stun worked), Depending on Calvin, willbreaker will limit next death to Cianna. Then it is all up to Shayd. I have had three times Willbreaker if Shayd is on her game. You end with Blood and Shayd. If Shayd is picked off, Blood gets that Double last hit.
