I feel that there are a number of rules that need some work how about you?
One rule I find needing the be changed is damage reduction. It worked for a while but now not so much.
5/magic for low level people is good
10/magic or higher is usually nothing for players about 4th level as everybody has a magic weapon or can have or a temp one
It just not the great defensive ability it was.
3.5 rule was 5/magic, 10/+2 weapon and so on. And the weapon needed have a plus two not just 2 pluses worth. I'm not sure that is the right answer either.
thoughts?
