I think it would be swell if members of a fireteam (members who are not leaders) could nominate a destination, still leaving the ultimate decision up to the leader.
Many times I've struggled with describing where to select a particular mission to a lower level friend. Granted, he could always just promote me to leader but there are other advantages.
-People who don't have working mics could communicate their preferred destination/ mission easier and quicker.
- a separate idea is matchmade fireteams (not matchmade strikes). I would love to have an option to select a difficulty level and be matched with a list of commonly leveled players and a selection of [insert difficulty level] missions to choose from. This is where mission nomination would REALLY play it's roll.
