Jondor_Battlehammer said:If Improved Sunder is overpowered, then it is because sunder is over powered. *sarcasm* I have no problem with it. It is a very powerful ability, but only if you have the desire and discipline to make constant use of it. I wouldn't use it, but if I did, I could make it very annoying for the DM. I gave it a 7.

The problem with sunder is it is only likely to succeed against inferior opponents because of the opposed attack roll. If you are fighting an inferior opponent in melee why aren't you killing him instead of destroying potential treasure? Why not just use disarm or grapple instead?
This is really only a compelling tactic for NPCs with good DR. Even then it is easily countered by GMW (or Magic Weapon). Your primary casters can easily defeat the DR of any creature they are likely to meet with GMW.
I am uncomfortable with sundering weapons because it only encourages PCs to rely on GMW. I doubt that is a good thing. It is also cheesy because it very easy for the DM to abuse it against the PCs, accidentally or on purpose. For those of you who like this feat, how many earth elementals have you ever seen futilely attempt to break a +3 weapon? The sundering tactic can be used against these creatures in the long haul unless the DM metagames on their behalf.
A DM who uses sunder in a fairminded way is only increasing the value of GMW in the long run.
