Discussing Pathfinder combat rules with a friend the other day, he asked, "Why not just drop the To-Hit and AC stats and just use CMB and CMD for all of it?" I just said "I don't know. Sounds like a cluster-foxtrot in the making."
But then I got intrigued. Is this a terrible idea, or crazy enough it just might work?
First of all, armor, nat armor, and shield don't do squat for CMD.
Second of all, the CMD numbers are completely borked and IME by mid levels without HEAVY specialization, it's near impossible to beat a monster's CMD. Good grief, trying to with iterative attacks...
If you want your noncasters to miss a lot more often and physical protection to become meaningless, I suppose this would be the system for you. What's the working title for it? "Casters' Paradise"?
Just have the ac items that don't add to CMD become DR...since your armor doesn't prevent you from being physically touched by attacks it would still make sense.
Other than a few factors CMB and CMD are 'To-hit' and 'AC' values. I consider them just another variation like 'melee attack bonus', 'ranged attack bonus', 'touch AC', 'flat-footed AC', et cetera. There are lots of specific situations which add or remove a few factors... these two just have different naming conventions in the rules. Which is kinda silly, and why I often call them 'maneuver attack bonus' and 'maneuver AC'.
