As one of the most important things in any games the new user experience should be updated in order to help new users have an understanding of the trials ahead of them.
What game systems do you think the training grounds should walk players through before dumping them into the world at large.
Personally I think that the training grounds needs to talk about...
Organizing a Party
Leaving a Party
Am I missing anything important?
From the community, things that could be explained in training grounds:
Expanded class job NPC, warp to job change city
VIP/Magic Stone explainer
NPC that points players towards out of game fan resources
Build guide NPC
Ingame ill mannered rules
Class NPCs to talk to
Veteran players be able to bypass tutorial zone
Prontera Library for players who have questions after leaving the training ground
