Studying mob damage Post-BB

Now if we can find out how much damage is reduced by defense (assuming it too is changed). Paladins already will have uber defensive since max STR (23 DEX, 4 INT/LUK) provides 1214 weapon defense base according to the formulas above. That's a 607 damage reduction if the system is the same. with crazy potential items, it is possible to get over 4000 defense. Paladins get Shield Mastery which, if it works the way I translated, will triple your defense while wearing a shield. Is there something I'm missing? 12,000 defense is crazy since it would require monsters to have 6,002 attack power to cause more than a point of damage. There's probably a lot I'm wrong with, so I could really use some aid with this.

EDIT:

 Spoiler

Found on Spadow's blog.

With those stats pre-BB, he would have 5,397 weapon defense post-BB at level 200.
