I really like the idea of certain chat channels only being accessible in taverns, helps to not break the immersion. It makes sense lore-wise that taverns would have the local information/gossip.
The idea is very good.. But theres a problem...
If the veteran only reads this CHAT once he is inside a tavern, it might be tough for new players to find veterans willing to stay some times inside taverns, which is not gonna happen...
And if the vetrans may READ their questions from outside a tavern, then theres no point in being in a tavern... and the chat will continue to be a mess with all kinds of subjects mixed.
Its very hard to find a solution... because nobody is gonna stay on a HELP channel to help people all the time... People will desire to stay on the main chat channel..... If they create a HELP chat channel, it will be empty...
Theres only ONE solution... Leave one main chat only, and allow all kinds of subjects on it !!
Whoever wants to talk in privacy, may join a private conversation on another tab, with that very specific person... This way, some newbie goes on global chat, finds someone willing to help, and PM him.... Or just talk on the global chat anyway, if he desires and doesnt mind the flow of mixxed information...
