The hp resetting should be revamped I agree, they should when outside of combat regain 1\10th of there hp every 10 seconds, this gives players 100seconds (1minute 40 seconds) to get back to the npc. This would be the time needed to have the player restock and go back.
The wiki I believe would be an amazing aspect and it'll look nice to have it working alongside the forums, But with the wiki comes Wiki managers and Wiki staff, probably an aspect released once the server grows to around 25+ daily. (I have faith for this server).
Cluescrolls sound like an amazing aspect to make into the game, clues are fun and enjoyable no matter where you are, wether it be irl, or ingames and I like hunting npcs myself for clues to do them, gives you something outside of pvming, gambling, skilling, to do.
