So, picked this game up after seeing it in the Humble Bundle.  Played through the first couple of scenarios in "Perils of the Lost Coast" and won both (lost a character in the first one) but the third "Black Fang's Dungeon" is all but impossible to finish in the time allotted.  I must need more people in my party I theorize.  I buy two more toons to fill out a party (mage and ranger).  Try to do the whole scenario over again.  Now I cannot even complete "Brigandoom!"  I time out EVERY time.   
  
I don't understand.  Why does the game get more difficult when I have more toons?  That makes no sense.  How would I ever beat a scenario?  Is it entirely up to RNG cards?  That seems really inefficient.  Like You cannot possibly win with regularity like that.  And I know this is not exactly mature but winning is fun, losing constantly is not.  And timing out is just lame. 
  
So what am I missing?  What am I doing wrong?  Where did I go off the rails because this started out fun and has rapidly become boring and lame.
