A little bit of fun trivia.

You all know the Novice Hall.
In my language there is two form a "you", a familiar one and a polite one.

Tank and DPS NPC have a familiar and energic tone using the familiar "you" when then explain what you will do.
But the Healer NPC use the polite "you" while explaining in a very polite and calm tone.

This difference is quite funny.
