I think that new status effect for waepons that decrase monster's defense would be good idea. It will be called "acid" or "corrosion" (I don't know which name would be better) and it will affect only one part of monster but resistance to this status after applying won't increase. If hunter want to apply this status effect quickly he/she should hit only one of monster's parts because it cummulates in one part. For example,when hunter cause some acid damage (which is not enough to cause corrosion) on head and he/she begin to hit wings instead head he/she will cause acid damage from beginning (old acid damage will still be on head) so it's good to hit only one part. It will not only increase damage taken by monster but also it will let weapon cut through part more easily and boost ability to break and sever parts. It will also have special effects on some monster (especially on these which can increase defense) For example, Zaboazagiru won't be able to create ice armor on acid covered parts. These weapons will be created from monsters which can decrase hunter's defense such as Deviljho or Chameleos.

Sorry if there are any mistakes. My english is not perfect.
