People who say "first time" in new content

[Gemina]

Why? What compels you to say something so obvious? I genuinely don't understand.

If you're referring to the duty itself notifying players that one or more players are new to the instance, it does not tell you which player(s) are new. A sprout icon also does not indicate that the player is new to the instance. I really don't know how it is so "obvious" until a player mentions that they are new.
