Played on hard mode - too easy... Repairment of baricades should cost money for sure. That willmake the game at least a bit harder. Last wave is a piece of cake if you maintain about 10 heavy guns in the building
My team is 2 rogues (front line - mostly using "Create opening, quickness >80) + Warrior (front line middle - using "Cleave", quickness 40) and Cleric (second line, using "Litany of Pain" for general damage or "Anoint" for warrior buff, quickness 70)
