First, would it be possible to improve the spawn at the Yew Graveyard? In an area surrounded by Reapers, Titans and Ogre Lords, it seems that the spawn in that place would be a lot more ferocious than just a couple of skeletons and a headless one. Newer players can't even consider hunting it because of its location, so I don't see how ramping that place up would impact that aspect of the game. Of course, I've been wrong before and will be again.
Second, we can make player clones disappear by saying "please go away" or "please leave." There are times when NPCs can be quite irritating, especially with their "conversation." Would it be possible for them to move away if asked nicely? I don't mean recall and they're gone, like the player clones. I mean, like across the screen or ten tiles away or something along those lines. They could even get all huffy and respond with: "Fine!" or "I can see when I'm not wanted!"
Anyway, just a couple of ideas.
