In W2 energy weapons does more damages vs heavy armored ; which leads to rangers nudity...
With this mod, armor gives log10(armor+1)*20% damage reduction. (eg : 2 armor points gives ~10% reduce, 5 armor ~= 15%, and 10armor ~=21%).
On top of that, each non-penetrated armor point gives an additional 10% reduce.
Finally, energy weapons damage doesn't depends on target armor anymore. Instead they have a permanent +50% damage bonus and ignore damage reduction.
