1) Move the loot room behind its own load-screen door, so the frequent spawning/despawning of items doesn't affect the performance of so many people. This is annoying enough while generally tooling around, but trying to log in while the spawn/despawn occurs turns your link red and drops you from the server.
2) Stick a lever or something in the dojo that, when activated, forces The Dojo Door to remotely spawn in the marketplace and/or elsewhere. You (Squeak) will likely never have to spawn the door manually again, and it will afford us night owls a much more convenient way of helping each other and our alts inside when you're not around. This should be safe to add as a permanent fixture without worrying about it bleeding through to live since it will be contained in the dojo itself.
3) Add a second set of kobolds, in a new room, that fight back when attacked. The freedom to quickly test defensive abilities against them instead of just offensive abilities would be great. Would also be nice if they lose aggro or leash if you try to leave that room (or put it behind a load screen), so you can get away easily to respec or w/e.
