This is some "outstanding" stuff I remember i did in the classic zones (got ported over). Probably this work might be of interest with the start of "working" classic zones.
-Butcherblock: Ogres spawn/act more natural
-Dagnor's Cauldron: extensive work here; almost all npcs now roam/aggro as they should
-Dagnor's Cauldron: NPC camp will provide protection
-Dagnor's Cauldron: No npc's stuck underwater anymore
-Dagnor's Cauldron: Added Bilge Farfathom spawn and made him hard to find as in live.
-South Karana: Quillmane spawn fixed to spawn as he should.
-Loottables were revamped (what good is plat if it drops common?
-Drops were revamped (who wants a drop that is too easy to get?)
-Many drops/named drops added and set with their proper drops and drop rate ( I still have a lot more of this to do)
-Quests: I have added hundreds of quests though out all the zones and many expansions; some of them very complex, others just simple, things the npc's say ("For the defense of Kelethin!!").
-Ships; What you see now is what I could manage tell I can figure out something else - I intend to have all "ship" zones with some kind of "tribute" to the classic boats that once sailed Norrath.
-all casters npc's default to "no pets" as should be, only special NPC casters will carry pets
