Provide an example army composition and stats that would be effective against a Lizardfolk horde. The issue is that the Barbarian has significant problems with both armor and defense stat progression. For example, if I needed to defeat a slightly leveled Swamp Thing, I know how to do it.
60 Goblins, 10 Wolves, 15 Orcs, 3 Rocs, and a hero of level 3, with increased attack and ballista skills, should be sufficient.
