Some pretty good ideas. I like the idea of making it so that attacking monsters from various angles has a more-realized effect.

Also, please keep my Marauder from missing 5 times per short battle. My dex is over 100 and I still miss quite often. And no missing on creatures that are standing still like crabs in their shells, sleeping sheep etc. It's pathetic when I miss, or the creature "evades" my attack when they're not even moving!
