recently there haven't been a lot of positives, but this unanounced change cleans up the landscape and lowers the amusment park atmosphere significantly.
Also I have no idea when you put him in but Hallor Calloway (delera's)... make more NPC's like him... explain the intricacies of the game in a way that is both informative and still fits into an RPG. Atmosphere + new player info is a win/win for everyone. Sprinkle 30 or 40 of these tip givers through Korthos and Harbor, marketplace and houses and get less basic and more advanced as you go.
Then naturally make a collection mini quest like Monster manuals or explorer poi's call it the "journal of wisdom". make it searchable and cross reference/link the MM
