SOE has announced another new feature coming as part of the Legacy of Ykesha expansion: an NPC chat journal tool.
This sounds like it will be a great advantage, and by itself may justify buying the expansion for some people. ...
I rarely did any questing back in the day when I played EverQuest. But when I did I always had a lengthy printout of the quest walk-through. With the NPC journal, I'd still be using the walk-throughs, but I might tend to follow up on other quests a bit more.
I'm not sure, but the impression I get is that this tool just keeps track of conversations. It doesn't actually organize them by particular quest. That's unfortunate: it would be great to be able to open a quest and see all the conversations you had had during its progress. Maybe they'll have that in the next expanion.
