I hope so! That would be massively useful. My assumption is there's some sort of randomizer element thrown into the mix, because battle results are never the result of a 1-for-1 ratio on Attack vs. Defense. Ranged attackers, for instance, don't always shoot down Melee fighters before they get to hit back.

If that's the case, precise predictions would be impossible, but some likely/worst case scenario outcomes aren't outside the realm of probability. :)
