I love what the Edain team has done with the Dwarven factions. giving them so much movie/book personality really makes up for them being one of the only factions with no cavalry.
Which brings me to the battle-wagons. I never use them in 4.1.1. because i feel like they got nerfed...HARD! like, even on 95% handicap, the enemy can destroy a battle-wagon easily (and i'm not talking just spearmen: orc warriors could destroy a battle-wagon with no problem).
I can totally accept a faction that has no cavalry, especially when it's the Dwarves (IH Dain kind of counts, but not really because he's just one hero), but is there a logical reason for nerfing battle-wagons? were they too OP in the base game/previous versions of Edain?
As far as suggestions, i would just say not to increase their attack, but to give them a few more hit points, just so that they don't die so easily.
