Particularly the DM rules? I know they updated a few things for the Player packet, and while it would be pretty cool to see a couple things added to this (backgrounds...) I think it stands up pretty well. But the Basic DM guide is in need of some more info. The monsters and rules to build encounters are there, but that's about it. The magic items are the same ones out of the starter set. This document dropped when the DMG was still in production so they put this warning in the document:
It is quite possible that the info in the current document is the only info we're going to get. And hey, I know they don't have to give us any more for free... BUT if their warning label is only intended to tell us they will only updated the current info within the packet, then why has nothing been done in 6 months? This leads me to think there will be more info added.
That said, why haven't we seen any updates yet, and when do you think we'll get a "final"** Basic document?
**I say this understanding that this will be a "living" document. However, the current Basic DM rules are incomplete. I'm thinking about when the Basic whole (Player/DM Rules) will be understood as complete, regardless of what 'living' rules might trickle in from time to time. Does that make sense?
Do you have the most recent version of the Basic DM rules (v0.3)? The "work in progress" text you cited is not in v0.3. There was a significant difference in v0.2 and v0.3 in terms of encounter building (the section that included the "work in progress" quote. v0.3 uses the version in the DMG.
