Just imagine it. Your looking for someone to do Trials, or the Raid, so you use an emote where your guardian just pulls out a sign that says LFG on it until you tell them to stop.
Now that's an emote I'd waste my money on.

Would make it much easier to see their guardian and equipment before accepting a random friend request and adding to fireteam only to boot 10 minutes later in the middle of a raid and have to search all over again
