just now, on DF2, the following topic was discussed:
creatures don't deal fixed damage, but rather a fluctuating damage within a fairly wide range, depending on randomness. And in the worst case, it can happen that in a quick match, your creatures will constantly deal maximum damage, while neutrals deal minimum damage. Plus, there's also the triggering of abilities, morale, and luck.
In the end, let people who play on 3.05 post their statistics here so we can see if there is a radical improvement after switching to this "super-cheating" version.
