The quest system is what drives any NPC's speech, and what drives any NPC to act in any way beyond the vanilla monster AI.
The emulator code provides the necessary support for a quest engine. But the responsibility for
writing all quests, even if the quest only scripts NPC speech, is beyond the scope of the stock eqemu code. From that standpoint, your request is actually out of place on this forum.
There are a few side projects that work on quest scripting among other things. (Edit: Insert shameless plug for
www.projecteq.net here
) If you're willing to learn the scripting, you can contribute the scripts you so want to see. If you're unable or unwilling to contribute, then you can offer your suggestion but ultimately the people doing the contributing will either agree with your priorities or not.
