Greetings,
I am following this Suggestion since the first post, and i have to say that what you guys made out of the first idea, which was already quite good, is simply great. Tolkien (or at least P. Jackson
) would be proud of you.
I vote for the first option, the small area DMG. I think that the Wheel Blades would rather slow the Battlewagon down, because it just hits more enemies.
Furthermore i think that the animals used by Erebor and the one by IH look the same, don't they?
PS: No idea if you noticed, but i am german, but you guys in the english forum have the best ideas
