I think that this hall is a good idea anyway. A nice place to learn your class / your job and what are the keys of it. But I don't think that it will help with the awful HL players behavior. For instance, I've seen a lot of low level tanks who were very good tanks, marking enemies, pulling a few enemies at a time, and so on. It's just that the endgame transforms all that good things in creating rushing farmers who just care about getting their tomestones and have no respect. It's like most of people change in this game once they arrive in HL... so well, this hall is still good but won't change anything at the end.
