It depends on your Team Powers, mines can deal with everything except the last Boss. Anyway starting with 3 or 4 Teams in the bottom left Camp does not change anything regarding the main "difficilty" (RNG) of the Map who is to reach the Boss of the North (only 2 Team can go North if you plan to get the 3 Stars).

EDIT: Finally they did it.
