Agreed. All those additional Lake-town characters were not really needed in my opinion.
If the Edain team wants to change the scout hero for the Iron Hills, I think it should be a dwarf.
Maybe this guy from War in the North?
http://lotr.wikia.com/wiki/Farin_(Champion)Farin is no-canon character as Murin and Drar. But I like this guy in this game(As one of few things) and he fought in the Battle of the Five Armies(He said this in the game).
I have some ideas for his abilities:
Level 1: Toggle Weapon - Switches between axe and crossbow.
Level 1: Patrol: Farin sends two soldiers to guard the selected area. Dwarven patrol has a high range of vision and can reveal nearby hidden units.
Level 3: War-cry: For 10 seconds Farin deals +25% attack and +25% speed
Level 8: Explosive Bolt: Farin shots explosive bolt to the enemy. The enemy in the selected area will gets moderate damage.
What do you think about it? You like this character?
