My friend and I are new to Edain and are both curious about all the factions and subfactions. We are playing through them to get a feel but don't really understand how one faction's units are different from another. We understand the rock, paper, scissors systems but Gondor's spearmen are probably better than Mordor's for instance.
How are the Dwarven subfactions different from another? What are each factions strengths and weaknesses?
