Actually, I was admitting that it's a complex problem and any changes will ripple through the system in hard to predict ways.

I am serious when I suggest that there should be a cap on damage reduction. Look at the damage reduction being used in this log: http://www.qhcf.net/phorum/read.php?3,668108,668108#msg-668108

Excessive damage reduction creates an arms race. Everyone starts needing every form of protection just to keep up with their enemies. If you cap damage reduction people are going to start worrying about ABS less and less because it won't do that much. They'll start doing other, hopefully more productive things in the game.

For the amount of work, discussion and heartache the ABS system causes, I don't think it's worth it. Overall, I'd rate it as a negative part of the game.
