Does someone have the calculation that's use to determine damage? Usually, it's Attack - Defense. However, it doesn't seem to be that way in LH.
Then, on top of that you place in the variable if a unit is defending or not. What does defending actually do? It certainly affects archers!
Attack and Defense both seem more like a power rating than an actual value, but as someone who's played Elemental for a long time, I've yet to figure out how the system works.
