In addition to falling accelleration (didn't they do high school physics?),,,
,,,I would like to see accelleration of the main character based on their weight (weight of equipment), so a heavy character couldn't side-step or dodge as fast as a unarmed character, but still have a similar top speed so they don't get bored on long walks.
Excellent idea! It would give an advantage to those of us who prefer a smaller, ranger style of combat. A nimble archer should be able to dodge an incoming attack much quicker than a lumbering warrior weighted down with heavy armor. I'm hoping they implement this!
