+1 on everything Carcass said. It's incredibly frustrating and a waste of healing resources to have the doorway blocked by lower AC party members.

Also, never forget the value of a quick close of the door too sometimes. For example, if you open the door and spot a number of rust monsters... shut that door fast and come up with a plan on how to deal with them, even if it means stripping down to do it.

There are a number of creatures that can be dangerous and are unable to open doors. Sometimes its simpler to not fight them or delay and come up with a plan on how to deal with them.
