This started off being a post about damage reduction, but in writing it I was finding I needed to talk more and more about defenses, because really DR is a subtopic of Defenses, so I started again.
Then I realized that I was finding it difficult to express me feelings on the various defense systems D&D has used, because they are much more complicated in aspect than the rules that define them. So I started again.
Then I found that in trying to express the fundamental aspects that make this such an important issue, I completely confused myself and I had written a wall on unmitigated garbage. So I am starting again, and I expect that when I finally get it written it will be both too long and too limited in scope.
So I am still writing, and still have a lot to say. I am just having trouble saying it.
I have also been thinking about other topics I want to cover. The main one is how important a solid system for making you own fantasy stories is. I also want to write a piece on the importance if location for both combat and non-combat encounters. Then i want to write about the difference between different types of combat encounters, and the different types of non-combat encounters. Then there is the skill system, the ritual system, the utility powers system, the leveling system, the three tiers introduced in 4E, the planescape, the monetary system and lots lots more.
Of course, there is also the Power System, and wether you want AEDU, Vancian, or some other system. This comes with another whole set of issues based on balance, speed, ability, roles and storytelling. All of these things I have an opinion on and ideas that might make them more flexible while keeping them simple enough to be tools rather than obstacles.
Then I think of the problem I am having just expressing my feelings on Defenses and I do not envy the designers trying to make this game better again. My deepest wish with these posts is maybe in someway for these posts to help the people with the impossible task to do it a little better or a little easier; though I know that is an unrealistic hope.
