If they have seperate options for the guild bank, i think it will be extremely powerful... ie guildmaster control checkboxes ala the current interface for:
- add items to Guild Bank
- remove items from Guild Bank
- use Guild Bank funds to repair
Having multiple controls will allow you to have "repair off" except for the nights / times the GM decides, not when XYZ players are doing heroic BlahdittyBlah and wiping 5 billion times.
I am very excited for Guild Banks, just hope there is the proper control in place to keep it in check. It elliminates the need for addons and web-interfaces to show bank contents, that is, if all guild members can *see* what is inthe bank, and not add/remove.
those types of permissions seem obvious, and i hope they arent overlooked
