Suicide Squad for farming Thief / Backstab Squad (Elite)

Girls Team

You Need:

1. One lvl 50 Thief/Rogue
2. Qriest blue+3, or Lady/Druid
3. Healer from a friend(Qriest or Rustbeard

Formation for the first two stages:

Healer, Rogue/Thief, Healer
Vacancy, Vacancy, Vacancy

Formation for Boss Fight:

1. Already got Thief in the first two stages

Thief/Rogue, Healer, Healer
Vacancy, Vacancy, Vacancy

2. No Thief in in the first two stages

Healer, Rogue/Thief, Vacancy
Vacancy, Healer, Vacancy

Problem with the above formation is that I kept getting shaman also.  I found a fail-proof suicide formation for farming thief.

Healer, blue rogue lvl 30, High lvl druid (must-have for resurrect)
Healer, vacancy, vacancy

Same set up throughout first stage to boss.

With this formation, rogue may sometimes die during stage 1 or 2 but very rarely.
