People who say "first time" in new content

[Seera1024]

Could you explain what you mean by that? Do you mean people don't know that it's new content?

Because at this point, many groups are a mixture of players who have done the content before and those who haven't.

People tend to be more forgiving to players doing something for the first time and well, the notice at the beginning doesn't tell you who the new player is.
