1) The ability to change class in a dungeon/raid, when a spot opens during the commencement of a duty. IE: You're doing Coil, and a tank leaves unexpectantly. You have a tank class that meets the requirement of the content you are running, but you can't change unless you leave. If there was a way to offer the chance to replace that class with someone with your party first, no one will leave and one of the more expendable classes (re: DPS) will be automatically filled by the DF.

2) There needs to be more options for the DF, especially for those playing multiple (re: ALL) classes. For example: I'll queue in for Turn 1 on my BLM, but maybe the queue time is too long, maybe I'd want to queue in for Hakkue Manor on my CNJ at the same time. Or perhaps since I have a 50 tank, healer, and DPS, I'd want to offer all 3 types of my services
