Why this game sucks. Penalty for leaving dungeon.

[Kraggy]

But if I happen to not think of asking if somebody is new to this dungeon, I expect the person who is new to the dungeon to speak up and tell everybody.

Given the behaviour of the jerk tanks and healers being discussed in this and other threads are you surprised when the newbie doesn't 'own up' to it? Frankly the 'you have a noob in your party' display should be removed given the attitude it has caused.
