Custom content - how much is too much?

[Bones]

I for one welcome custom content and it sounds like a lot of fun. What I had in mind was adding more substance to already existing content without changing the dynamic and feel of classic too much. Example = more quests. For a game called everquest there is a distinct lack of quests in the old world and I feel like there is a literal fuckton of room for more quests and content and items to be added to existing zones and npcs. One of the many things I liked about vanilla WoW was exactly this; dozens of quests in each zone.
I also love the idea of adding custom zones in like the ones that you see on old world maps that were never implemented into classic.
It would also be cool to see pvp style battlegrounds (much like existed in WoW) later in the timeline. I know at one point years ago the staff was actually working on something like this but it was shelved for lack of time and resources when other more important priorities existed at the time (Velious/Kunark).
It's going to be hard for work to be done on anything though when they are having to constantly babysit the raid scene.
